Method and circuit for estimating motion between images of two interlaced fields, and digital signal coding devices comprising such a circuit |
摘要 |
<p>The method involves using a channel (10a) to find the movement vector which best represents the movement between two frames. The channel consists of two non-autonomous branches which are placed at the outputs of the substages of the frame vector searching channel (20). The vector frame is found by block correlation and a refining operation is performed to find the middle of the image. This allows determination of an approximation of the movement vector which can be used accurately in the estimate. <IMAGE></p> |
