Abstract:

Recent work carried out, in England, on optical flow techniques in computer vision is described. The background, principles and implementation of the algorithms derived for machine perception and interpretation of visual motion are discussed in order to give an overall picture of developments to date. It is concluded that we have a first attempt at devising a system for using visual motion to obtain 3D scene information at the level of Marr's 2 one-half D sketch. The algorithms proposed can b...
