Line 11: Applying the motion vectors to an image to predict the transformation to another image, on account of moving camera or object in the image is called [[motion compensation]]. The combination of motion estimation and motion compensation is a key part of [[video compression]] as used by [[MPEG]] 1, 2 and 4 as well as many other [[video codecs]]. Motion estimation based video compression helps in saving bits by sending encoded difference images which have inherently less ~~energy~~entropy as opposed to sending a fully coded frame. However the most computationally expensive and resource extensive operation in the entire compression process is motion estimation. Hence, fast and computationally inexpensive algorithms for motion estimation is a need for video compression. == Evaluation Metrics ==
