Paper Abstract

This paper proposes an accurate deinterlacing algorithm using a maximum a posteriori (MAP) estimator. First, we produce accurate motion vector fields between the current field and adjacent fields by employing an advanced motion compensation scheme that is suitable for an interlaced format. Next, the progressive frame corresponding to the current field is found via the MAP estimator based on the derived motion vector fields. Here, in order to obtain a stable solution, well-known bilateral total variation–based regularization is applied. Then, at a specific mode decision step, it is decided whether the result from the aforementioned temporal deinterlacing is acceptable or not. Finally, if the temporal deinterlacing is determined to be inappropriate by the mode decision, a typical spatial deinterlacing is applied instead of the MAP estimator-based temporal deinterlacing. Experimental results show that the proposed algorithm provides at maximum 2 dB higher PSNR than a cutting-edge deinterlacing algorithm, while providing better visual quality than the latter.
