Statistical analysis of pathological motion areas

Abstract

We address the problem of complex events in degraded image sequences. The occurrence of these complex events causes the failure of the motion estimation process. Consequently, the sequence of operations that rely on it, such as motion compensation and motion picture restoration, will fail as well. We present a statistical analysis of such areas, as well as a taxonomy of pathological motion. The results indicate that it is possible to discriminate between the complex events resulting from complicated object motion and those resulting from image artefacts. An analysis scheme is proposed for the task of discriminating between the two cases. (28 pages)
