Abstract
This paper presents some adaptive search range strategies at both frame and macroblock level for B pictures coding in H.264/AVC. First, a basic frame-level search range scaling strategy is proposed based on the linear motion relationship between P and B pictures, which is only suitable for normal or low motion situation. Then, an improved frame-level adaptive search range scaling (F-ASRS) algorithm is proposed by taking full advantage of intra mode and motion vector statistics. F-ASRS algorithm can precisely detect the global motion degree and adjust the search range of next B picture in advance. The local motion is further studied according to the information of the adjacent previous coded blocks, and then a macroblock-level adaptive search range (MB-ASR) algorithm is proposed. When integrating F-ASRS with MB-ASR, the search area of B pictures can be greatly reduced without any coding performance loss.
