Real-Time Fade Detection in Compressed Domain
Zhengming Li, Huifang Qu, Jin Zhang · 2008
A fast and effective fade detection algorithm is proposed in this paper, which directly operates in compressed domain and suitable for real-time implementation. By analyzing the prediction directions of B frames, which are revealed in the macroblock types, the candidate fades can be found. Then, uncommon intracoded macroblocks of the P frame can be applied as an indicator of fade. As a result, locating fades are operated by a sliding window. Extensive experiments illustrate that the proposed algorithm achieves superiority measured by recall and precision rates, providing a useful technique for fast and on-line video content processing.
