Abstract: Shot boundary detection method based on Structure Perserving Projection（SPP） is proposed. In order to extract more effective video features, the SPP is presented. The adject matix of SPP is constructed based on mainflod structure not on space structure, and the singular value problem of SPP is resloved by QR decomposition method. Shot boundary is recognized with Support Vector Machine（SVM）. The experimental results show that the proposed method is powerful and effective for shot boundary detection.
