Abstract
Contours made of sequences of adjacent edge points are used as
primitives in stereo pair matching. Matching contour segments, rather
than the traditional epipolar edge points, can greatly reduce possible
ambiguity. This is done by reformulating point-matching constraints to
apply to contour matching, and by introducing a unique incremental
matching scheme. Best-matched contours are paired first, constraining
through neighborhood support their neighboring contours. Examples of the
proposed stereo matching scheme are shown, with very few errors, for
aerial images of natural terrain
