ABSTRACT:
A process for obtaining a motion vector for motion estimation used in a video image analysis, utilizing a block matching algorithm, which has the effect of reducing the computational load that is placed on the hardware logic used for implementation of the process. In a process of obtaining the absolute error value for the compared image block, a preliminary comparison is performed for every processed pixel in the image block to determine if the set minimum value of the absolute error function represented by a motionless tolerance constant is achieved. It is not necessary to obtain every actual value of the absolute error function. The block matching scheme of providing motion estimation enables hardware implementing the process to discontinue processing if the desired motion vector is selected prior to all image blocks being compared.
