    • The motion estimation unit (100) comprises a block-matcher (102) for calculating a start motion vector (110) by minimizing a predetermined cost function as a matching criterion for the block (116) of pixels with a further block of pixels (122) of a further image (120). The motion estimation unit (100) further comprises an optical flow analyzer (104) for calculating an update motion vector (111) based on the start motion vector (110) and which is designed to find the most appropriate set of optical flow equations corresponding to respective pixels of the block (116) of pixels. This is achieved by analyzing gradient vectors of optical flow equations for pixels of the block (116) of pixels. Finally the selector 106 of the motion estimation unit (100) selects the motion vector (126) by comparing the start motion vector (110) with the update motion vector (111).

    • The motion estimation unit (100) comprises a first summation means (106) for calculating match errors of a number of candidate motion vectors of a segment (116) of a first image (118). The motion vector with the lowest match error can be assigned to the segment (116) as the estimated motion vector. The match error is based on summation of absolute differences between pixel values of the segment (116) and pixel values of a second image (120). In order to estimate the deviation of the estimated motion from the true motion vector, i.e. the motion vector error (130), the motion estimation unit (100) further comprises a second summation means (108) for calculating a variance parameter by summation of absolute differences between pixel values of the segment (116) and pixel values of the first image (118) and estimation means (110) for estimating a motion vector error (130) by comparing the match error with the variance parameter.
    • 运动估计单元(100)包括用于计算第一图像(118)的段(116)的多个候选运动矢量的匹配误差的第一求和装置(106)。 具有最低匹配误差的运动矢量可以被分配给段(116)作为估计的运动矢量。 匹配误差基于片段(116)的像素值和第二图像(120)的像素值之间的绝对差的总和。 为了估计估计运动与真实运动矢量(即,运动矢量误差(130))的偏差,运动估计单元(100)还包括第二求和装置(108),用于通过绝对值的和来计算方差参数 (116)的像素值与第一图像(118)的像素值和估计装置(110)之间的差异,用于通过将匹配误差与方差参数进行比较来估计运动矢量误差(130)。
