发明名称 APPARATUS AND METHOD FOR TWO-DIMENSIONAL DATA COMPRESSION
摘要 A system and method for compressing data, including image data. The image data is formed by a pixel array, the pixel array having target pixels and prior pixels, each prior pixel being located in a position within the pixel array prior to each of the target pixels. The method of the present invention includes compressing the image data to obtain a compressed image. In the compression step, the pixel array is traversed according to a predetermined non-linear two-dimensional traversing pattern. A longest matching prior pixel string, if any, is located for each string of target pixels having a string of matching prior pixels. If no matching prior pixel is found for a target pixel, each such target pixel is characterized as an unmatched pixel. Finally, the compressed image is encoded and may be either transmitted or stored.
