阅读:57发布:2021-03-31

专利汇可以提供ADAPTIVE MOTION ESTIMATION METHOD AND APPARATUS专利检索,专利查询,专利分析的服务。并且In an apparatus for performing a motion estimation (ME) on a block (BL) within a current frame based on a predetermined reference frame (PRF), a difference block (DB) forming channel provides a DB representing a difference between the block and a corresponding reference BL. And a ME path deciding circuit (321, 323, 325) provides a zero vector if AV TH2 and then provides the SB's as a set of second BL's (SBL's) if TH2 TH3, wherein TH1, TH2 and TH3 are preset thresholds, respectively. A first ME circuit (350) performs a ME on a sample BL obtained by subsampling the first BL within a first predetermined search region (PSR) in a sample reference frame by using a first block matching method (BMM) employing a predetermined full search technique (PFST) to generate a first MV. And a second ME circuit (360) carries out a ME on each of the SBL's within a second PSR in the PRF by using a second BMM employing a predetermined logarithmic search technique to generate a set of second MV's corresponding to the SBL's. And a third ME circuit (370) executes a ME on each of the TBL's within a third PSR in the PRF by using a third BMM employing the PFST to generate a set of third MV's corresponding to the TBL's.,下面是ADAPTIVE MOTION ESTIMATION METHOD AND APPARATUS专利的具体信息内容。
