摘要：Given an image with an unwanted feature, a collection of pixels (a definedregion) entirely containing the unwanted feature is designated, and replacement data

values for the defined region are generated, thereby healing the unwanted feature. Aselected image region is healed by propagating values in a boundary region intoreplacement data values for the selected image region by iteratively applying aprocedure or algorithm (e.g., iteratively applying one or more kernels), such that valuesin the boundary region are continuously put back into the iterative calculations. Anexample of such a function uses kernels to generate replacement data values havingmultiple orders of continuity at the boundary. Optionally, replacement data values for animage region to be healed are generated based on a difference between existing datavalues and texture data values, thereby introducing texture (e.g., pattern, noise)components to a resulting healed region in the image. Mutiresolution processing andtiling can also be used to enhance performance.
