The 3-D Recursive Search Block-Matching algorithm was introduced as a high
performance low-cost motion estimation algorithm suitable for demanding scan rate
conversion applications. The figure below explains the principle of the block matching
algorithm. The result is a best matching vector, which contains information about velocity
and direction of a block at position (x,y).
