Abstract

It is observed that arc length of a contour does not change if that contour is moved in the direction of motion on the surface. A function measuring arc length change is defined. The direction of motion of a contour undergoing motion parallel to the image plane is shown to be perpendicular to the gradient of this function. This gradient approximates the direction of motion when object motion in the scene is not parallel to the image plane or when perspective projection is used. This method has been implemented and is shown to compute the ST (spatiotemporal) surface flow in sequences of edge images and gray level images.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
