Abstract(in English) | We use a second-order differential constraint and a noise estimation hypothesis to create a probabilistic distributions of optical-flow. The second-order differential constraint contains a Hessian matrix; calculation of its inverse, in general, is not stable. The proposed method avoids inverse calculus of Hessian matrix and uses an assumed noise distribution to overcome this problem. The resulting probabilistic distributions contain flow information and represent the characteristics of the local structure of the image; edge point distributions are elongated, and basically flat points result in flat distributions. The probabilistic distributions can be integrated within equally moving points, and the results are limited in narrow area which permits optical flow estimation. This method depends on just local calculus, no recourse is made to exceptional processes. |
