| Abstract: | Shot detection is the key technology in the content-based video retrieval and browse.The video structure and the shot types are summarized.Several typical shot detection algorithms are analyzed and discussed.A shot detection algorithm based on SVD and feature-level fusion is proposed.The frame's reconstructed matrix is given through the sub-space projection,and then the histogram feature as well as the SVD's value difference between the frame and its reconstructed matrix is computed.A shot detection is processed after feature-level fusion.The experimental results prove the algorithm efficient. |
