A Motion Detection Algorithm Based on Background Subtraction and Three Frame Differencing MO LIN 1, LIAO PENG2, LIU XUN3 (Department of Computer and Electronic Information, Guangxi University, Nanning ,China 530004) Abstract： An algorithm based on background subtraction and three Frame Differencing is presented in this paper. Firstly, a background model is based on Surendra algorithm, then the moving object region is gained using background subtraction, and then, the background subtraction is combined with three frame differencing to detect the motion information. The simulation results show that the presented algorithm runs quickly and veraciously, and fits for real time detection.
