20080285806 | Method for Estimating Motion and Occlusion - This invention relates to digital image and video processing. It is concerned with determining the motion of pixels between frames in an image sequence. That motion relates to the motion of objects in the scene. The invention determines two kinds of motion information at each pixel site. The first kind of information is the displacement between a pixel site in the current frame and the corresponding site in me previous or next frame. This is the motion vector at that site. The second is an indication of whether that pixel is occluded or not in the previous or next frames. This allows any subsequent processing to take advantage of the fact that the pixel in the current frame may have been covered in the next (or previous) frame by some object moving over it (or revealing it). The invention also allows for prior knowledge of objects that are to be ignored in the process of motion determination. | 11-20-2008 |
