| Abstract: | This paper proposes a fast search algorithm for motion vecter estimation in moving image compression.This analysis and experiments show the computational complexity of this method is much lower than 2D full search algorithm, while the matching pertbrmance is obviously better than three step algorithm, and the hardware realization is simple. So it is suitable for real-time video coding. |
