 Storage area and temporal based optimized run length codec for classic jpeg image compression (sat-borl codec) patent thumbnailStorage area and temporal based optimized run length codec for classic jpeg image compression (sat-borl codec)
This invention optimizes the entropy encoding part of jpeg (joint photographic experts group) image compression by modifying the run length encoding method that performs the actual compression by removing the redundancy from transformed and quantized image data. Using the fact that the preceding processes of run length coding, in jpeg compression algorithm, produces a large number of zeros, the original run length coding uses an ordered pair (a,b), where ‘a’ is the length of consecutive zeros preceding the ascii character ‘b’.
