Shot Cut Test Based on Mathematics Parameter and Chain Code

Abstract

In this paper, An effective shot cut detection algorithm directly in DCT domain was proposed. This algorithm(including abrupt change and ) test the n -1 frame and n frame through the extracting the feature vector of each frame. When extract the features of frame, two-dimensional mathematics parameter m1-s from DCT coefficients without its inverse transform and 8 directional chain code was computed, Divide m1-s space into 30 unequal partitions (subspaces) and compute the numbers pr within the 30 subspaces (entries) as the feature vector to judge the different of the two frames. locating shot cuts is operated by comparison tests.
