2006 International Conference on Intelligent Information Hiding …, 2006•ieeexplore.ieee.orgThis paper introduces an unusual event detection scheme in various video scenes. The
proposed method finds out the video clips that are most different from the others based on
the similarity measure. Each video clip is represented by the motion magnitude and direction
histograms and color histogram. Without searching key-frames, we calculate the similarity
matrix by using\chi^ 2 difference or chamfer difference as the similarity measure of features
in different clips. Finally, we apply n-cut clustering. Clusters with low self-similarity value are …
