Abstract: |
A method based on predicted direction correction/statistical prejugament for estimating fast sub-pixel movement features that in the estimation of sub-pixel (1/2, 1/4, or 1/8) movement, the result of movement estimation with high search precision and the statistical inforamtion under current precision are used to prejudge the current movement vector, and the search stop creterion is used. Its advantages are little distortion, simple operation and high precision. |
