In this paper, we propose a FFT based full search BMA(block matching algorithm) with SSD(sum of squared difference) criterion.The proposed method focus on the relationship between the cyclical cross-correlation and the SSD criterion.By using FFT to calculate the cross-correlation between data in different sizes, the proposed method has a large increase in speed of block matching.Especially, when the intended block is made up of real signals we can finish matching two intended blocks in one time.In the simulation of motion estimation,it shows that the proposed method is more accurate than the conventional method with SAD criterion and is faster than the conventional method with SSD criterion.Compare to the direct SSD full search, the proposed method's processing speed is 10 to 700 times faster. |
