The present invention relates to an image editing system. RELATED APPLICATIONS This application claims benefit of U.S. Provisional Patent Application No. 60/450,078, entitled "Image Blending By Guided Interpolation", specifically incorporated herein by reference for all that it discloses and teaches. TECHNICAL FIELD The invention relates generally to image editing, and more particularly to blending an image. BACKGROUND OF THE INVENTION Editing digital images, particularly digital photographs, is a common activity in both domestic and professional contexts. One common task includes pasting a piece of one image into another image or into other locations of the same image. This operation is useful for repairing, correcting, and modifying digital images. For example, in FIG. 1, a user wishes to insert a sun 100 from a source image 102 into a destination image 104. In a simple copy-and-paste operation, the user would select or "clip" around the perimeter of the sun l00 in the source image l02, copy the clipped region, and paste the clipped region at the desired location within the destination image 104. Alternatively, a simple drag-and-drop operation may be employed in a similar maimer. However, in both approaches, the boundary (or "seam") between the inserted clipped region and the rest of the destination image 104 would appear abrupt and reflect any irregularities in the clipping operation. Furthermore, any portion of the sun's background (i.e., a solid light blue in a color image) in source image 102 that was captured in the clipping operation would appear as a stark discontinuity when inserted into the destination image 104, in which the sky is represented by a gray hazy background. In other words, the inserted clipping would not blend into the destination image 104. An alternative approach, called "cloning", involves an anchor point defined within a source image. A paintbrush control is used on the destination image to define the region of the destination image into which the source image data should be copied. The results are similar to the copy-and-paste or drag-n-drop alternatives. In addition, other image editing operations can also involve altering the appearance of a selected region of an image. For example, texture in a region of an image may be flattened, a background or foreground may be decolorized, or illumination changes may be performed on a region of the image. However, such editing operations also introduce problems with seams between the edited region and the rest of the original image. To improve the results of these existing approaches, a local "feathering" operation may be performed to conceal the seams between the inserted clipping and the destination image background. Such a feathering approach typically involves blurring or smearing the image data at the seam to approximate a smooth transition between the inserted clipping and the destination image background. However, a feathering operation may produce unsatisfactory results because the seam is merely replaced with blurred image data. Furthermore, the existing approaches fail to provide a variety of blending modes to allow a user to best integrate an inserted image portion into a destination image. Therefore, the existing clipping and cloning approaches fail to satisfactorily provide flexible and seamless image insertion and editing in many common scenarios. SUMMARY OF THE INVENTION Embodiments of the present invention solve the discussed problems by providing a blended result image using guided interpolation to alter image data within a destination domain. The destination domain may be altered based on a guided interpolator that is either dependent or independent upon a source image. A variety of interpolation guides may be used to yield different effects in the blended results image. In implementations of the present invention, articles of manufacture are provided as computer program products. One embodiment of a computer program product provides a computer program storage medium readable by a computer system and encoding a computer program that computes a blended result image from a destination image. Another embodiment of a computer program product may be provided in a computer data signal embodied in a carrier wave by a computing system and encoding the computer program that computes a blended result image from a destination image. The computer program product encodes a computer program for executing on a computer system a computer process for computing a blended result image from a destination image. A destination domain having a boundary is defined in the destination image. A guided interpolator, including an interpolation guide and a boundary condition associated with the boundary of the destination domain, is provided. The blended result image is computed based on the guided interpolator to satisfy the boundary condition at the boundary of the destination domain and to minimize a difference across the destination domain between the interpolation guide and a gradient of the blended result image. In another implementation of the present invention, a method of computing a blended result image from a destination image is provided. A destination domain having a boundary is defined in the destination image. A guided interpolator, including an interpolation guide and a boundary condition associated with the boundary of the destination domain, is provided. The blended result image is computed based on the guided interpolator to satisfy the boundary condition at the boundary of the destination domain and to rninimize a difference across the destination domain between the interpolation guide and a gradient of the blended result image. In yet another embodiment of the present invention, a system for computing a blended result image from a destination image is provided. A domain definition module defines a destination domain having a boundary in the destination image. An interpolation guide datastore provides a guided interpolator including an interpolation guide, and a boundary condition associated with the boundary of the destination domain. A blending computation module computes the blended result image based on the guided interpolator to satisfy the boundary condition at the boundary of the destination domain and to minimize a difference across the destination domain between the interpolation guide and a gradient of the blended result image. These and various other features as well as other advantages, which characterize the present invention, will be apparent from a reading of the following detailed description and a review of the associated drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Embodiments of the present invention provide a blended result image using guided interpolation to alter image data within a destination domain. The destination domain may be altered based on a guided interpolator that is either dependent or independent upon a source image. When blending a source region into a destination region of an image, guided interpolation can eliminate or minimize apparent seams between the inserted region and the rest of the image. Furthermore, a variety of interpolation guides may be used to yield different effects in the blended results image. Such interpolation guides may include without limitation an identity guide, a smooth guide, a filter guide, a transparent guide, a masking guide, and a weighted average combination of various guides. FIG. 1 depicts a source image, a destination image, and a blended result image in an embodiment of the present invention. The source image 102 includes a source region 100 containing a sun. A user wishes to insert and blend the source region 100 into the destination image 104, which does not initially include the inserted sun at location 108. In a first operation, the user defines the source region 100, such as by dragging an outline around the source region 100. Alternative methods of defining the source region 100 may be employed, including without limitation setting in anchor point for a cloning brush, selecting an element in the image, specifying a color characteristic of a source region, or specifying coordinates in the source image 102. Generally, digital image data is represented by pixel values. For example, a black and white digital image may be represented by a vector of pixel intensity values, each vector element corresponding to an individual pixel. In contrast, a digital image data for a color image may be represented with multiple values for each pixel. For example, in the RGB (red, green, blue) color space, each pixel is presented by intensity values for each of three color channels. Other color spaces are also contemplated, including without limitation LC1C2 and CIE-lab space. It should be understood that to merely copy-and-paste the source region 100 into the destination image 104 would typically result in an irregular blue-sky-colored border or seam 110 around the sun, overlaying the darker night sky background 112 of the destination image 104. A seam typically appears as an abrupt change in color, brightness, features, texture, etc. as compared to the destination image. As such, to produce a more realistic result image, blending of the inserted source region 104 can obscure or eliminate the visibility of the seam 110 in the result image 106. Accordingly, as shown in the result image 106, the source region 100 has been inserted and blended into the destination image 104 to produce a realistic effect. FIG. 2 depicts a conceptual blending of two one-dimensional functions in an embodiment of the present invention. This description regarding FIG. 2 provides a conceptual demonstration of a blending operation involving one-dimensional "images". It should be understood, however, that various types of blending operations are contemplated within the scope of the present invention, including without limitation the two-dimensional blending operations described with regard to other figures herein. A first intensity function A is shown in destination graph 200, representing a one-dimensional destination "image". A second intensity function B is shown in a source graph 202, representing a one-dimensional source "image" that is to be inserted into the destination image of graph 200. The blended result function is shown in a result graph 204, representing a one-dimensional blended result "image". Dashed lines 206 represent boundaries of the source region and the destination region. In another embodiment of the present invention, the source and destination regions may have disparate sizes and shapes (e.g., rectangular, circular, irregular), both of which may be altered by the system to be more compatible for blending. In one embodiment of the present invention, a user wished to use the blending operation to merge the source region into the destination region, such that the image data at the boundary of the destination region is blended to appear realistic. In the illustrated embodiment, this is shown conceptually by connecting source region of the first intensity function A to the boundary points of the second intensity function B. As such, the blended result function illustrates a combination of the two intensity functions. In order to eliminate, minimize, or otherwise reduce the appearance of seams, the boundary conditions of the component functions are blended such that the values of each component functions are equal as the functions approach the boundary points 208 and 210. Fig 3 illustrates a blending of two two-dimensional image regions in an embodiment of the present invention. To extend the conceptual description of the one-dimensional blending of FIG. 2, an example of two-dimensional blending is provided in FIG. 3. A destination image 300 shows a dark water surface. The corresponding intensity data associated with the destination image 300 is shown in the two-dimensional intensity graph 302, where intensity may include a mono-color intensity (such as white in a black-and-white image or a single color channel in a color image) or some other appearance signal (e.g., a component or aggregate value of LC1C2, etc.). For example, note that as the destination image 300 becomes lighter near the top, the intensity of white shown in the intensity graph 302 increases. In an intermediate image 304, a source region 312, which contains a reflection of the sun on a different water surface, has been inserted into the image. In the illustrated embodiment, the destination region is defined as the region of the image overlapped by the source region 312. Prior to blending, the seams between the source region and the rest of the destination image are very apparent, as shown in the intermediate image 304, at least in part because of the difference in the color of the water. This can also be seen in the non-blended intensity graph 306, in which the intensity data relating to the source region 312 is abruptly visible at 314. In the blended result image 308, the source region has been blended into the destination region to provide a realistic image of a reflection of the sun on the water surface. Changes in the intensity of the image data in the source region are apparent in the blended result intensity graph 310, where the intensity data of inserted source region has been blended to match the intensity data of the destination image at the boundary of this first region, thereby decreasing the overall "brightness" of the source region. FIG 4 depicts a source image, a destination image, and a blended result image in an embodiment of the present invention. A destination image 400 shows (in a color image) the light green surface of the ocean at a beach. A source image 402 shows (in a color image) two children in a swimming pool, in which the water appears light blue. For the purpose of this discussion and to map image features to the algorithms described herein, the destination image 400 is referred to as "f*", and the destination region 404 in the destination image 400 is referred to as "Ω". The boundary 412 of the destination region 404 is referred to as "Ω". Likewise, the source image 402 is referred to as "g*", and the image data of the source region 416 is referred to as "g", and. In the blended result image 410, the source region 416 has been blended into the destination region 404 to produce the composite result image comprising image regions 418 and 420 (the blended image data f within Ω, and the remaining portion of f *, i.e., the portion of the destination image outside of the destination region). Note: The blended result image was generated by inserting source regions containing each child into the destination image sequentially. In one embodiment of the present invention, the blending operation is implemented using the following functional minimization as a guided interpolator (or "minimizer"): having the boundary condition f \Ω= f* |Ω, where (Equation Removed) is the gradient operator. In addition, other interpolators may be employed, such maximization functions and functions that optimize to a given goal, threshold, or range. The associated Euler-Lagrange equation, i.e., the condition met by the guided interpolator, is known as the Poisson equation with Dirichlet boundary conditions: ∆f = ∆g- over Ω with f |Ω = f* \Ω, (Equation Removed) The guided interpolation approach may be more generally represented by the following functional minimization as the guided interpolator: having the boundary condition f|αΩ=f* \αΩ, where v represents an interpolation guide and / is referred to as an "interpolant". Calculus indicates that the functional minimization is the unique solution of Poisson equation: ∆f = div v over Ω with / |αΩ = f* |αΩ , where div v = — - + — is the divergence of v = [u, v] . fix dy Various choices of v permit blending if a variety of ways, as shown in the table of example interpolation guides below, although other interpolation guides are contemplated within the scope of the present invention. (Equation Removed) For example, the identity interpolation guide / results in no change to the destination image (thus,f = f*). Alternatively, the smooth interpolation guide S alters the destination image. The associated Euler-Lagrange equation for the smooth interpolation guide S is: (Equation Removed) over Ω with f\αΩ=f |αΩ and is known as the Laplace equation with Dirichlet boundary conditions. The unique solution fof the Laplace equation with Dirichlet boundary conditions is often referred to as the "membrane interpolant". Solving a discretized version of this problem in each color channel leads to a very smoothed or blurred image region in the domain Ω. The Smooth interpolation guide S minimizes the gradient inside the domain ("null guidance"), and results in a very smooth interpolation of the colors lying on the border of the domain. The Smooth interpolation guide S can be used by computer graphics region filling algorithms, including polygon and arbitrary shape filling algorithms. Exemplary effects of the transparent and masking interpolation guides are shown and discussed with regard to FIGs. 7 and 8, respectively. FIG. 5 depicts a blending system in an embodiment present invention. An image editing system 500 receives a destination 504, such as image data for a destination image. A destination selection module 508 receives the selection of a destination region within the destination 504. As previously discussed, the destination region may be defined by a pasting operation, a cloning operation, an outlining operation, or other methods of selecting a region of the destination image. In at least one embodiment, the image editing system 500 also receives a source 502, such as a source image. A source selection module 506 receives the selection of a source region within the source 504. It should be understood, however, that alternative embodiments, such as those involving a smooth interpolation guide or a masking interpolation guide, do not require a source or a source selection module because the interpolation guide is independent of any source. A domain definition module 510 receives the selection or selections and defines a destination domain (and possibly, a source domain). In one embodiment, a domain definition may be in the form of ranges of X and Y coordinates on an image, although other means of defining a domain are contemplated within the scope of the present invention, including without limitation arrays of image locations and region-defining algorithms. An image data collector 511 collects the image data contained within the destination image, the destination domain, and possibly the source domain, in the input image(s), which have been represented herein by the functions f*,.f* over Ω, and g, respectively. A blending computation module 512 receives the destination domain definition, the destination image data, and possibly the source region information. In addition, the blended computation module 512 uses these input to compute image data for a blended result image 516 based on an interpolation guide, derived or accessed from information stored in the interpolation guide datastore 515. The image data for the blended result image 516 is received by the output module 514, which can render the blended result image 516 on a display or output the image to a storage device or another application. FIG. 6 depicts operations for blending in an embodiment of the present invention. A receiving operation 600 receives a selection from a source (e.g., a source region). Another receiving operation 602 receives a selection of a destination (e.g., a destination region). A defining operation 604 defines a source domain based on the selection from the source. Another defining operation 606 defines a destination domain based on the selection from the destination. A collecting operation 608 collects the image data contained within the destination image, the destination domain, and possibly the source domain, which have been represented herein by the functions f*, f* over Ω, and g, respectively. A providing operation 610 provides a guided interpolator, such as by accessing a datastore or providing a hard coded algorithm. A computing operation 612 computes a blended result image from the collected image data and the guided interpolator. An output operation outputs the blended result image to a display or other output device. FIG. 7 depicts blended results derived from a Transparent interpolation guide in an embodiment of the present invention. A source image 700 is blended into a destination image 702 using the Filtering interpolation guide F to produce a blended result image 704. However, it is clear from the result image 704 that the space between and within the letters of the word "BLEND" are not realistically rendered. In contrast, a second interpolation guide, called Transparent, is applied to produce a blended result image 706. The algorithm for Transparent is given in the table above. An alternative representation of the Transparent algorithm is: (Equation Removed) The Transparent interpolation guide T, at each location in the destination region, selects the image gradient (either from source image data or from destination image data) that is the greatest. In this manner, the blended result image comprises image data that best matches the most apparent features of either the source region or the destination region in a given location in the destination domain. FIG. 8 depicts a blended result derived from a Masking interpolation guide M in an embodiment of the present invention. In a Masking interpolation guide, the gradient if optimized to satisfy a predetermined criterion, including without limitation being below a threshold, above a threshold, within a given range, and meeting a given goal. As shown above, the Masking interpolation guide M filters the destination image data such that only the most salient features are generated in the destination region of the blended result image. For example, using the Masking interpolation guide M shown in the previous table, image data intensity in a source region 804 of a source image 800 is attenuated for low (or, alternatively, high) gradient regions to produce a cartoon-like effect, shown in blended result image 802. Alternatively, the Masking interpolation guide M may be modified to provide a band filter range: (Equation Removed) FIG. 9 illustrates blending into the destination image outside the dimensions of the source domain in an embodiment of the present invention. A destination image 900 is shown with a destination region bounded by a destination boundary Ω 902. A blending region T 906 is bounded by a blending boundaryT 904 on the inside and the destination boundary Ω 902 on the outside. A guided interpolator may be provided to perform some amount of mixing in the region T between destination boundary Ω 902 and blending boundary T 904: having the boundary condition f |Ω = f* |Ω. The magnitude of the mixing effect in this region may be controlled by the weighting parameter a. The exemplary hardware and operating environment of FIG. 10 for implementing the invention includes a general purpose computing device in the form of a computer 20, including a processing unit 21, a system memory 22, and a system bus 23 that operatively couples various system components include the system memory to the processing unit 21.

A basic input/output system (BIOS) 26, containing the basic routines that help to transfer information between elements within the computer 20, such as during start-up, is stored in ROM 24. The computer 20 further includes a hard disk drive 27 for reading from and writing to a hard disk, not shown, a magnetic disk drive 28 for reading from or writing to a removable magnetic disk 29, and an optical disk drive 30 for reading from or writing to a removable optical disk 31 such as a CD ROM or other optical media. The hard disk drive 27, magnetic disk drive 28, and optical disk drive 30 are connected to the system bus 23 by a hard disk drive interface 32, a magnetic disk drive interface. 33, and an optical disk drive interface 34, respectively.
