%X In order to extract histogram information from the Compressed Video Stream rapidly, proposed a fast way to extract histogram from the H. 264 Compressed Video Stream, explaine the principle of this algorithm and describe its implementing procedure in detail. This algorithm is based on the information derived from the partially-decoded video bit stream, using the statistical method to get the histogram rapidly. Experimental results show that the presented algorithm can provide satisfactory results, and the computational complexity is significantly reduced. This algorithm can be used in the region of Shot Segmentation, Video Retrieval, and etc.
