摘要

Shot boundary detection is the first step of the video processing. Based on the summary of the existing methods of shot boundary detection, this paper put forward an adaptive dual threshold algorithm which adjusts automatically the threshold along with the changes of the content of shots. Color histogram of weighted non-uniform blocks is taken as characteristic to calculate differences of frames in the algorithm, which considers not only the global information of the image, but also the local information. The second detection is carried on when the boundaries are detected initially reduces effectively error rate that caused by flashlight. Finally, the algorithm is proved effective.
