Generation of MPEG-7 descriptor in compressed domain
We propose a technique for generating the MPEG-7 descriptor in compressed image/video data. Image processing in the transform domain is a much interesting area recently because compressed image and video data are becoming widely available with the data format like MPEG or JPEG. In general, processing in the transform domain requires smaller data quantities, and lower computation complexity than that in the spatial domain. In this paper, we propose a generation algorithm of the MPEG-7 metadata in the compressed domain. We have developed an algorithm to get the homogeneous texture descriptor in the compressed domain.
