Abstract:
1. A system for modifying images that assigns color intensity values to pixels in an exposed pixel region subject to image manipulation operations, said system comprising: means for using color intensity values of pixels in a non-exposed pixel region in an original image, and means for assigning new color intensity values to pixels in the exposed pixel region, said new color intensity values are similar to color intensity values of pixels in a pixel region surrounding said exposed pixel region so that the exposed pixel region blends smoothly with the surrounding pixel region, wherein said means for assigning said new color intensity values is based on a color intensity value function determined at a location of a pixel, wherein said color intensity value function used to assign said new color intensity values to said pixels in said exposed pixel region is determined by fitting a function to known color intensity values of said pixels in the pixel region surrounding said exposed pixel region, wherein said means for assigning said new color intensity values at said location of said pixel locates a mirror-image pixel by a hypothetical mirror placed along a boundary of the exposed pixel region.
