Abstract :
The high probability of mistake for optical flow (motion vectors) calculation is theoretically proved. The experimental ratings for quantity of abnormal (incorrect) vectors, calculating by the most known methods are given. It is offered to add two-dimensional motion vectors with third component: the estimation of its reliability. It is obtained by using the mathematical methods of fuzzy logic. The offered estimation allows considerably reduce the influence of abnormal vectors, and also sharply decrease computing loading
