摘要： A motion estimation method and apparatus for video coding of a multi-view sequence is described. In one embodiment, a motion estimation method includes identifying one or more pixels in a first frame of a multi-view video sequence, and constraining a search range associated with a second frame of the multi-view video sequence based on an indication of a desired correlation between efficient coding and semantic accuracy. The semantic accuracy relies on use of geometric configurations of cameras capturing the multi-view video sequence. The method further includes searching the second frame within the constrained search range for a match of the pixels identified in the first frame.

摘要： A system for compressing digital data by representing a portion of it predictionally and transformationally as a block of transform coefficients, then quantizing that block selectively into a set of encoding symbols based on an indication whether the transform coefficients represent the portion as having a particular characteristic, and then by encoding the set of encoding symbols into a data bit stream. In particular, frequency may be used as the characteristic of the digital data in many applications.

摘要： Systems and methods for optimizing system performance in variable length decoding systems are described. Embodiments are described in which decode tables are analyzed and elements of the tables sorted by probability of occurrence. Storage of elements can be determined by probability of occurrence and embodiments of the present invention can optimize system efficiency by storing most likely entries into fast-memory and least likely entries in slowest memory. In certain embodiments, a single large table is provided that cannot fit into decoder fast-memory. In some embodiments, individual elements can be optimized for storage in fast-memory by selecting more frequently occurring entries or groups of entries into decoder memory.

摘要： A framework for efficient sum of absolute difference (SAD) computations for variable block size, sub-pixel motion estimation is presented. Simultaneous, or parallelized, SAD computations can be performed by storing and re-using previous SAD computational information, which can speed up the performance of a motion estimation module by reducing the number of cycles necessary to perform a particular motion estimation algorithm.
