An algorithm is a well-defined sequential computational technique that accepts a value or a collection of values as input and produces the output (s) needed to solve a problem. Or we can say that an algorithm is said to be accurate if and only if it stops with the proper output for each input instance.
A Block Matching Algorithm is a way of locating matching macroblocks in a sequence of digital video frames for the purposes of motion estimation. The underlying supposition behind motion estimation is that the patterns corresponding to objects and background in a frame of video sequence move … See more Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another; usually from adjacent frames in a video sequence. The motion vectors may relate to the whole … See more A metric for matching a macroblock with another block is based on a cost function.
