Abstract:
An image includes a plurality of image blocks each including a plurality of pixels and having an associated motion vector. The image is processed by selecting an image block and a corner region (E1x) located in a corner of the selected image block to provide a selected corner region. A plurality of adjacent image blocks located adjacent to the selected corner region are then selected from the plurality of image blocks. The motion vectors assigned to the adjacent image blocks are then compared to determine if the motion vectors form a homogeneous vector field. When the motion vectors of the adjacent image blocks form a homogeneous vector field, a motion vector for the corner region is generated from the motion vectors of the adjacent image blocks. When the motion vectors of the adjacent image blocks do not form a homogeneous vector field, the motion vector for the corner region is set equal to the motion vector of the image block.
