โœฆ Synopsis

In this paper, we propose a content-based moving picture expert group transcoding method using a discontinuity feature in the discrete cosine transform (DCT) domain. A DCT block is transcoded differently depending on the height of dominant discontinuity within a block. In the experiment, we show the result that the video quality of content-based transcoding is better than that of a constant cut-off method and the processing time of the adaptive method is much lesser compared with the pixel domain methods in the same bandwidth.

Automatic video indexing is an important feature in the design of a video database. Recently, compressed domain techniques have become popular due to their inherent advantages of efficiency and lower complexity. On the other hand, wavelet transform has emerged as a powerful tool for efficient compre
