摘要： The refinement of a lower-pel resolution motion estimation vector is made more effective by preceding the actual refinement with a determination of a context out of a set of context candidates based on coding costs of a set of lower-pel resolution vectors within a neighborhood of the lower-pel resolution motion estimation vector, wherein each context candidate is associated with a ranking among a set of higher-pel resolution candidate vectors surrounding the lower-pel resolution motion estimation vector. The actual refinement of the lower-pel resolution motion estimation vector to obtain the higher-pel resolution motion estimation vector may thus use the ranking associated with the context determined: sequentially arranged accordingly, the set of higher-pel resolution candidate vectors may be tested sequentially.

摘要： A technique for encoding a video signal includes generating a representative value for each block of one or more video frames by applying a predetermined function to the pixels of the respective block. To perform a block matching operation for a current block, the technique applies the predetermined function to the current block and interrogates representative values of blocks at specified locations in a spatial and/or temporal vicinity of the current block to find a matching block whose representative value matches the one generated for the current block.

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 (45) of candidate values (20, 21, 22, 23). When the chosen candidate value (23) 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 (30) beyond the extreme value (23). When this new candidate (30) then has the lowest matching error, additional new candidates are chosen until it no longer has. An apparatus for adapting a video signal (40) uses the chosen candidate values to create an enhanced version of the video signal (40).

摘要： During digital video signal processing, the knowledge of position and time modifications in the recorded scene is utilized for data compression and format conversion. In general, expensive computer circuits are necessary for conducting high-precision estimation of motion. The inventive hybrid method comprises simple measures which can be clearly executed and provide a low-cost high-precision estimation of motion. According to the invention, a block vector BV is generated in a number of steps for each block. To begin with, a first modified block matching occurs in order to select a start vector SV from a number of vector candidates VCi. The start vector SV is then refreshed by pixel recursion and used as an additional start vector VCi+1. Finally, a block matching resulting from coordinating the first and second steps in a third step produces the final block vector BV. The block vectors BV are read out for a successive generating of a dense motion vector field and for new vector candidates VCi which are to be intermediately stored.
