Method and apparatus for real-time lossless compression and decompression of image data

摘要: A method and apparatus for lossless compression decompression of video image data. Video data is composed the RGB, YUV or gray scale (color) information each pixel frame Storage such can require large amounts The present invention provides individual frames Each processed in n×n blocks. combination colors (called color list) number different block then determined. If above a predetermined threshold, no occurs. below searches prior occurrences than performed. In some instances, list contiguous blocks will be same. this instance, map representing positioning output. Further, encountered stored as an entry cache. cache subsequently used dictionary. instances where it's cache, index to into represent found block. need not with compressed stream since it reconstructed during stream.
