Motion vector estimation employing adaptive temporal prediction

摘要

The present invention provides an improved method for motion estimation and in particular for a motion compensated interpolation. By taking the source of the video data into account, a spatial offset for selection of a temporal prediction vector is set in accordance with the detected source mode. By selecting an appropriate offset from the current block position in a previous field, the accuracy of the predicted motion and, consequently, the picture quality of motion compensated interpolated images can be increased considerably.
