Experiment Study on Fast Half Pixel Search Methods of Motion Estimation
() Abstract
In this paper, three methods of fast half pixel search of motion estimation have been proposed. Experiments show the three methods have good MSE performance and decoded picture quality; Analysis show that the slowest method can save compute times about 29.17% and the most fast can save about 58.33%. The proposed methods can be as candidate algorithms for the real time implementation of motion estimation half pixel search.
