Blockbasierte Bewegungs- oder Tiefenschätzung |
摘要 |
In block-based motion or depth estimation, a block is assigned a motion or depth value as a result of minimizing the matching error over a limited set of candidate values. The matching error for each element of the set is obtained by computing the luminosity differences between a block of a first image ( 10 ) and an area of a second image ( 11 ). It may occur that an object ( 12 ) is partially obstructed by another object ( 15 ), so that a pixel ( 14 ) in the block is not present in the corresponding area, because another pixel ( 16 ) overlaps it. The method and system according to the invention determine which pixels are not visible in the second image ( 11 ), and compute the matching error over only the visible pixels. An apparatus for adapting a video signal ( 40 ) uses the chosen candidate values to create an enhanced version of the video signal ( 40 ). |
