Scene content classification from MPEG coded bit streams
Ali M. Dawood, M. Ghanbari · 1999
We propose a classification method of MPEG coded video based on the image texture and motion levels of the scene content. The texture and motion are divided into three levels each, low, medium and high, resulting into nine scene categories. Since in MPEG-1 (and MPEG-2) encoder the DCT coefficients of the I-frame are affected by the image texture, while the motion affects the macroblocks coding mode of P- and B-frames, hence, an automatic scene classification can be obtained from the coded bit stream based on the scene's texture and motion levels. The method is useful for the content-based video analysis, such as video modeling and MPEG-7.
