Scope of motion research: from image intensity changes to semantic abstractions
The author outlines the broad scope of research endeavours that involve visual temporal change. It is acknowledged that several classes of researchers with differing backgrounds such as psychophysics and neurophysiology, as well as computer vision, artificial intelligence and computer graphics, are active in the area of motion research, and that their interaction may be of benefit. In general terms, these endeavours are those of quantification of intensity changes in image sequences, representation of visual temporal information, temporal reasoning and event description, motion generation, animation, control structures for coordinating the above into a unified computer system whether it be a vision system or an animation system, and studies of biological visual systems, both psychophysical and neurophysiological. Motion understanding is briefly described in terms of its three main components: sensing motion, perception, interpretation and description of motion; and motion generation. In an attempt to deal with the complexity of complete motion understanding systems, hypotheses and models are drawn from the vast literature available in some of these different classes. 40 references.
