Tow Phase Auto Identification and Query of Similar Video Clips Based on Fuzzy Histogram
Aiming at the problem of auto-differentiation of similar video clips, a coarse to fine two phase method is presented, which take into account both effect and efficiency. Firstly, Feature point set and corresponding trajectory are obtained based on fuzzy color histogram feature vector. Secondly, Position density histogram in the feature space of the video clip is computed and elementary quick filtration is implemented based on this statistical feature. Finally, More accurate differentiation is performed using simplified time sequence trajectory after the elementary quick filtration.
