With the unique characteristics of triangular inequality and non-singularity, Bhattacharyya distance has been proposed as a viable scene change metrics. It outperforms much better than the other two in that it calculates and maximizes the feature vector distance between muhi-modal clusters in a hyper-sphere space. The experiments are conducted and the precision recall sta-tistics are compared, and the results support our analysis. %K scene change detection %K feature vector distance %K Bhattacharyya distance %K Chi-square distance
