Abstract
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 ( ). When the chosen candidate value ( ) is an extreme value of the set, it is impossible to predict how remote this value is from the real minimal matching error. To overcome this problem, the method and system for choosing an optimal candidate value choose a new candidate ( ) beyond the extreme value ( ). When this new candidate ( ) then has the lowest matching error, additional new candidates are chosen until it no longer has. An apparatus for adapting a video signal ( ) uses the chosen candidate values to create an enhanced version of the video signal ( ).
