Abstract
A method is proposed to compute the direction of heading from the differential changes in the angles between the projection rays of pairs of point features. These angles, the image deformations, do not depend on viewer rotation. The key problem of separating the effects of rotation from those of translation is solved at the input. Experiments show both the feasibility of the method on real images and the advantages of using deformation rather than optical flow
