0 = fx 0 a; y 0 bg I 1 = (ffx x 0 ; z z 0 g 0 =: 1 g; ;) 1 = fx a; z z 0 g Hence, the original constraint can be simplied to C 1 = f:s(a; z 0);r(a;z 0)g, which is easily refuted by looking up s(a,c 50) and disproving r(a,c 50). It should be quite obvious that the advantage of the additional exibility provided by our mechanism heavily depends on a good procedure for deciding whether to take an e...

The examples in Figure 16 and Figure 17 demonstrate how system errors have a cascading effect, resulting in multiple errors being introduced into a single hypothesis string. The alignment examples shown are, by design, easy to understand and are easily derived. In practice, multiple errors frequently occur in a single hypothesis string resulting in many different possible alignments. The Scorin...

A method for directly computing i :age motion at corners is presented. The method is based on temporal intensity gradients along lines parallel to the sides of the corner. The results of applying the method to two time-varying images are discussed. The support of the Defense Advanced Research Projects Agency and the U.S. Army Night Vision Laboratory under Contract DAAG53-76-C-0138 (DARPA Order ...
