ABSTRACT:
The present invention provides a method and apparatus for detecting occluded areas in a video frame. A previous displacement vector field, DVF, is motion compensated (402) and used to provide an occlusion test parameter (404) which is compared to an optimal threshold (408) to detect occluded areas. The optimal threshold is calculated based on the previous DVF and a predetermined threshold (406).
