Complex event classification in degraded image sequences

We address the problem of motion estimation failure in degraded image sequences. This failure is caused by some complex events that take place in the image. As a result, the sequence of operations that rely on the motion estimation process, such as motion compensation and motion picture restoration, fail as well. The statistical analysis of the complex event areas indicates that it is possible to discriminate between the complex events resulting from complicated object motion and the ones resulting from image artefacts. An analysis scheme based on segment matching is proposed for the task of classifying the detected complex event areas.
