Abstract
An apparatus and software for processing an image reduces the number of pixels constituting the image by sequentially eliminating alternate rows and columns of pixels, the information represented by each pixel being eliminated (a “source” pixel) being redistributed into adjacent “destination” pixel locations. The redistribution is made in proportion to the similarity between the source and each destination pixel, e.g., similarity of color and/or luminance values.
