Image processing

摘要

A method of processing video signals containing multiple images. The method comprises dividing a first image into regions and associating a first plurality of regions of the first image with a first image layer and a second plurality of regions of the first image with a second image layer. Motion estimation is performed on pixel values that are derived from pixel values associated with the first image layer, substantially in isolation from pixel values associated with the second image layer, to generate a first motion vector field, and the first motion vector field is used to perform motion-compensated processing on pixel values that are derived from pixel values associated with the first image layer. The result of the motion-compensated processing is combined with pixel values that are derived from pixel values associated with the second image layer to generate an output image.

1. A method of processing video signals representing multiple images, comprising:
identifying pixels in an image that should not be included in performing motion compensation of images in the multiple images; using a hole-filling process to replace the identified pixels with values generated from values in a background image to form a hole-filled image; performing motion estimation on the hole-filled image to generate a motion vector field; using the motion vector field to perform motion-compensated processing on the hole-filled image; and combining a result of the motion-compensated processing with the identified pixel to generate an output image.
