A method fo quantifying inter-field motion in a video frame

摘要

A method of quantifying inter-field motion in a video frame (10), the method comprising generating from the video frame (10) a top field (20) and a bottom field (30), interpolating each of the top field (20) and the bottom field (30) so generated to produce interpolated top and bottom field images (40, 50) and comparing the interpolated top and bottom field images (40, 50) to each other to determine a value representative of the amount of inter-field motion present between the top field (20) and the bottom field (30).
