New method of optical flow evaluation

The effective method (referred to as an image functionalization method) of an optical flow evaluation is stated in the report. The functionalization method differs from the well know gradient method in operating not upon the image intensity functions but upon values of a special functional, determined on a set of the image intensity functions. On the base of that approach a functional relation equation is derived. That equation is an analogue of a brightness constancy constraint equation used in the gradient method of image registration, but it does not hold spatial derivatives of image density functions. That brings considerably new features of universality and accuracy to the technique of the image motion parameters estimation as the equation encloses spatial derivatives of the applied functional kernel only. The functional relation equation establishes a fundamental linkage between measurable characteristics of dynamic images and its motion parameters. It represents a generalization of gradient group methods. This method is free from main principal shortcomings of the ordinary gradient method. As a result the method gives an opportunity to solve different difficult problems of registration such as varying brightness images registration, different color images interconnecting and others.)
