Research on Compressed-Domain Image/video Processing Techniques

To be efficient, most of the multimedia data are stored and transferred in their compressed format. However, multimedia applications also require flexible processing of the data to make full use of them. The traditional methods treat compression and processing separately. As for compressed data, it must be decompressed firstly, which is very ineffective to the overall performance of the multimedia applications. So, the compressed-domain processing techniques of multimedia data are addressed to improve the situation. In this paper, we discuss the compressed-domain image processing techniques in details. Some current problems and important future directions are also presented.
