Abstract :
A method for quickly and reliably selecting and matching points from three views of a scene is presented. The points that are selected are based on the concept of epipolar gradients, and consist in stable and relevant image features. Then, the selected points are matched using edge transfer, resulting in a measure of consistency for point triplets and the edges on which they lie, with the camera system´s trinocular geometry. This matching scheme is invariant to image deformations due to changes in viewpoint.
