The paper describes the combination of several novel algorithms into a system that obtains visual motion from a sequence of images and uses it to recover the three-dimensional (30) geometry and 30 motion of polyhedral objects relative to the sensor. The system goes on to use the recovered geometry to recognize the object from a database, a stage which also(More)
A relaxation algorithm for the computation of optic flow at edge elements (edgels) is presented. Flow is estimated only at intensity edges of the image. Edge elements , extracted from an intensity image, are used as the basis for the algorithm. A matching strength or weight surface is computed around each edgel and neighbourhood support obtained to enhance(More)
