Block matching method

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. The most popular in terms of computational expense is: Mean difference or … See more 1. http://www.mathworks.com/matlabcentr… 2. See more Block Matching algorithms have been researched since mid-1980s. Many algorithms have been developed, but only some of the most basic or commonly used have been described below. Exhaustive Search This algorithm … See more WebFor the exact matching method, the exact matching algorithm is automatically used. For the fuzzy matching method, various fuzzy matching algorithms can be used. Each matching algorithm is scored based on how closely it matches the two fields. For example, if you select exact matching and the two fields match, the match score is 100.
