In this letter, we present a new method for the motion detection/compensati
on between opposite parity fields in interlaced video sequences. We introdu
ce a phase-correction filter, which is applied to one type (even or odd) of
fields before motion detection/compensation. By means of this phase-correc
tion filter, the motion-compensated PSNR has been improved by more than 2 d
B, on average. We also present a new deinterlacing algorithm based on the n
ewly developed motion detection/compensation. This algorithm requires stori
ng one field only, and the phase-corrected field is used for both motion de
tection/compensation and intrafield deinterlacing, thus making the proposed
algorithm computationally very efficient. Excellent deinterlacing results
have been obtained.
