Shot Boundary Detection Based on Macroblock and DC Image
Zhulin Tao, Xianglin Huang, Xi Wang · 2009
In this paper, shot boundary detection (SBD) algorithm based on macroblock and DC image is presented. We get the macroblock type information and simultaneously extract DC images from MPEG compressed domain. The statistics of macroblock type information is applied to coarse detection, and DC images are applied to scrutiny detection. The results of experiments show that our algorithm is efficient, and of low time consumption, hence the overall performance of the system is greatly improved. For its good performance in real time detection, SBD can be applied to online video shot detection and multimedia net.
