  • Method of processing a digital image by means of ordered dithering technique description
    Publication number: 20050280871
    Abstract: A dither matrix is applied to a high-resolution image to compare the value of each of the pixels that compose it with a threshold value of the matrix and to obtain an output value of the matrix (Dither matrix value) from each comparison. To each pixel value of the image there is applied an algorithm involving simple but displacement operation, namely shifts to the left and shifts to the right. The pixel values of a low-resolution image are output from the applied algorithm.

  • Method and system for processing image signals and computer program product therefor
    Publication number: 20050117805
    Abstract: A digital video image is compressed by determining for a group of adjacent pixels the global error values that result from the available combinations of truncation and integration of data strings associated with the group of pixels. A combination of truncation and integration that produces a minimum global error value is identified and used to control compression of the individual strings of data associated with the group of pixels.
