Abstract
A blended result image is computed 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 not dependent upon a source image. When blending a source region into a destination region of an image, guided interpolation eliminates or minimizes apparent seams between the inserted region and the rest of the image. 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 filtering guide, a transparent guide, a masking guide, and a weighted average combination of various guides.
