| Abstract: | A fast algorithm to detect motion in the compressed domain for video surveillance is presented. The algorithm partially decompresses the video bit stream and performs motion detection from its quantised discrete cosine transform coefficients. The very low computational cost makes this algorithm very useful when real-time motion detection has to be performed simultaneously in several video bit streams |
