    • A method and apparatus for estimating motion of a pixel block in a first frame, the method including searching a first area in a second frame to identify a first matching block that corresponds to the pixel block, the first matching block including a first error value that is a minimum of at least one error criteria between the pixel block and the first matching block, calculating a first motion vector associated with the first matching block. The method further including searching a second area in the second frame to identify a second matching block that corresponds to the pixel block, the second matching block including a second error value that is a minimum of the at least one error criteria between the pixel block and the second matching block, calculating a second motion vector associated with the second matching block and selecting a final motion vector between the first and second motion vectors based on the first and second error value.
    • 一种用于估计第一帧中的像素块的运动的方法和装置,所述方法包括搜索第二帧中的第一区域以识别对应于所述像素块的第一匹配块,所述第一匹配块包括第一误差值, 是像素块和第一匹配块之间的至少一个误差标准的最小值,计算与第一匹配块相关联的第一运动向量。 该方法还包括搜索第二帧中的第二区域以识别对应于像素块的第二匹配块,第二匹配块包括作为像素块与像素块之间的至少一个误差准则的最小值的第二误差值 第二匹配块,计算与第二匹配块相关联的第二运动矢量,并且基于第一和第二误差值选择第一和第二运动矢量之间的最终运动矢量。
