Abstract：A video hashing based on Locally Linear Embedding (LLE) is proposed in this paper. In this method, some representative frames are first selected based on a graph model, and four-order cumulants are taken as features of video in the high dimensional feature space. Then the video is mapped to a three-dimensional space using LLE, and video hash sequence is generated using the norms of points in the three-dimensional space to detect video copies. Experimental results show that the video hashing has good robustness and discrimination.
