The emphasis is on the key-frame extraction technique in content-based video retrieval. Dealing with problems existed in the traditional clustering algorithms, an improved shots key-frame extraction algorithm based on fuzzy C-means clustering is presented. Using the color feature information in the video frames, and then through the improvement of the clustering algorithm of video sequences to acquire...
An improved shots clustering key-frame extraction algorithm based on entropy is presented. Using the color information in the video frames, the algorithm looks every frame of a shot as a special sample and selects appropriate feature. And then through the improvement of the clustering analysis of video sequences to acquire the center value of various classes and the membership degree of every sample...
