Video indexing in the wavelet compressed domain

The multitude of visual media-based applications demands sophisticated compression and indexing techniques for efficient storage, transmission and retrieval of images and video. A variety of wavelet based video compression techniques have been reported in the literature. However, there has been little work done in the area of video indexing in the wavelet domain. This is crucial for consideration of wavelets as a potential candidate for multimedia applications, including standards such as MPEG-7. In this paper, we first present a brief review of wavelet-based indexing techniques. We then propose a video indexing system in a wavelet compression framework. Simulation results show that the proposed system provides a good indexing performance at a low complexity
