Video Shot Detection Method Based on Wavelet Transform and Wavelet Entropy

  • Received Date: 05 Sep 2007

  • A detection method for video shot transitions based on wavelet transform and wavelet entropy was presented.The mean and standard deviation of the low frequency components of an image is used to detect cut transitions.To detect gradual transitions,the wavelet entropies of the image in horizontal,vertical and diagonal directions are used as characteristic values,and these values are taken as inputs to calculate the Euclidean distances between neighboring images.A gradual transition is determined if at least two Euclidean distances are larger than a preset threshold in the detection window.Experiment results indicate that using the proposed method the ratio of correct detection is 95% and the detected ratio is 96% respectively for cut transitions,and 87.5% and 83.8% respectively for gradual transitions.
