A New Motion Estimation Method and Its Application in Motion Compensation Deinterlacing Algorithms.

In this paper, a new method of motion estimation is presented to replace the widely used method which calculates SAD to find the matching block. This method calculates the absolute difference between corresponding pixels of current block and reference block. Then according to the value of the absolute difference, different weights are assigned to these pixels. The level and value of these weights are set empirically. According to the sum of the pixels' weights, we can select motion vector and process motion compensation. This method avoids the error caused by few noise pixels when calculating SAD. The simulation shows this method can improve the quality of motion compensation in deinterlacing.
