Paper Abstract

Software implementation of multimedia compression is an enabling technology for the widespread use of computer based multimedia communications. M-JPEG offers reasonable compression at reasonable computational cost. This paper presents modifications to the well-known JPEG compression algorithm to achieve a 60 - 70% speedup of digital video compression. The scheme presented exploits dependencies between frames to predict the DCT coefficients in a frame based on previous frames in the sequence. This knowledge is used to reduce the computational complexity of the DCT transforms. The process-based approach introduces only a mild overhead of about 0.4% into the compression. Performance measurements with real video sequences demonstrate the increased performance of the modified JPEG process for digital video.
