Paper Abstract

We present a psycho-visual and analytical framework for automatic measurement of motion activity in view sequences. We construct a test-set of video segments by carefully selecting video segments form the MPEG-7 video test set. We construct a ground truth, based on subjective test with naive subjects. We find that the subjects agree reasonably on the motion activity of video segments, which makes the ground truth reliable. We present a set of automatically extractable, known and novel, descriptors of motion activity based on different hypotheses about subjective perception of motion activity. We show that all the descriptors perform well against the ground truth. We find that the MPEG-7 motion activity descriptor, based on variance of motion vector magnitudes, is one of the best in overall performance over the test set.
