Motion vector

In video compression, a motion vector is the key element in the motion estimation process. It is used to represent a macroblock in a picture based on the position of this macroblock (or a similar one) in another picture, called the reference picture.
The H.264/MPEG4 AVC standard defines motion vector as:
motion vector: A twodimensional vector used for inter prediction that provides an offset from the coordinates in the decoded picture to the coordinates in a reference picture.^{[1]} ^{[2]}
