Abstract This paper discusses shortcomings of adjacent-frame difference. Based on the image energy and high order statistic (HOS) theory, background reconstruction constraint con-ditions are setup. Under the help of block- processing technology, background is reconstructed quickly. The DSP based platform tests indicate that the background can be recovered lossless in about one second, while moving regions estimations are not influenced by target speed.
