Abstract

JPEG picture compression and related algorithms are not only used in still picture compression, but also to a growing degree for moving picture compression in telecommunication applications. Real-time JPEG compression and decompression are crucial in these scenarios. We present a method to significantly improve the performance of software based JPEG decompression. Key to these performance gains are adequate knowledge of the structure of the JPEG coded picture information and transfer of structural information between consecutive processing steps. Our implementation achieved an 80% performance increase decompressing typical JPEG video streams.
