Motion is inherent to video signals, and high perceptual quality cannot be achieved without accounting for motion. Although the information inferred from motion vectors in an encoder does not always represent the true motion of objects, in this paper, we show that it still carries useful information for finding an estimate of motion characteristics. We use the number of copy-mode macroblocks to measure motion intensity, and we use motion history to capture the spatial distribution of motion. By… CONTINUE READING
