Modern displays and the introduction of video in personal computers attract a lot of attention for de-interlacing technology. In this paper, a subjective assessment of various de-interlacing techniques is presented and compared with the popular PSNR metric. We used paired comparison, and tested five very different algorithms including inter-and intra-field linear, edge dependent, motion compensated and content adaptive intra-field methods. Our study reveals that the subjective scores of the de-interlacing techniques is highly correlated with the objective PSNR criterion.

Abstract-A de-interlacing algorithm using adaptive 4-field global/local motion compensated approach is presented. It consists of block-based directional edge interpolation, same-parity 4-field motion detection, global/local motion estimation and compensation. The edges are sharper when the directional edge interpolation is adopted. The same parity 4-field motion detection and the 4-field local motion estimation detect the static areas and fast motion by four reference fields, and the global motion estimation detects the camera panning and zooming motions. The global and local motion compensation recover the interlaced videos to the progressive ones. Experimental results show that the peak signal-to-noise ratio of our proposed algorithm is 2 3 dB higher than that of previous studies and attain the best quality of subjective view.

A four field variable block size motion compensated adaptive deinterlacing method is proposed to improve the accuracy of the motion vectors and lower the occlusions of motion compensated deinterlacing. The proposed de-interlacing method consists of variable block size motion estimation/compensation with four field SAD, interlaced block mode decision, and new block modes. The variable block size motion estimation/compensation improve the accuracy of the motion vectors, especially for spatially-periodic patterns. The new block modes and the interlaced block mode decision make block decisions more precisely, and special patterns that motion compensation cannot be compensated are correctly deinterlaced by these two methods. The subjective view shows the improvement of the accuracy of the motion vectors and the correctness of the mode decision.
