专利汇可以提供MOTION ESTIMATION AND SEGMENTATION FOR VIDEO DATA专利检索,专利查询,专利分析的服务。并且In an encoder, an offset processor (307) generates picture elements with sub-pixel offsets for a picture element in a reference frame. A scan processor (309) searches a frame to find a matching picture element and a selection processor (311) selects the offset picture element resulting in the closest match. The first frame is encoded relative to the selected picture element, and displacement data comprising sub-pixel data indicative of the selected offset picture element and integer pixel displacement data indicating an integer pixel offset between the first picture element and the matching picture element is included the video data. A video decoder extracts the first picture element from a reference frame and generates an offset picture element in response to the sub-pixel information by interpolation in the reference frame. A predicted frame is decoded by shifting the offset frame in response to the integer pixel information. The invention allows encoding with shift motion estimation and segment based motion compensation with sub-pixel accuracy.,下面是MOTION ESTIMATION AND SEGMENTATION FOR VIDEO DATA专利的具体信息内容。
