Abstract:

The codeword space was reduced according to calculating the longest interval so that codeword is never recurred by other variable in tuple, and the interval is not stored in codeword, thus 6tuple based codeword is replaced by 5tuple. The experimental result shows that the new codebook model is as fast and accurate as the original model. Moreover, the memory space demanded is reduced.

Key words: moving object detection, codebook model, codeword structure, 5tuple based codeword
