Paper Abstract

In order to eliminate the effect of edge aliasing and blurring caused by deinterlacing algorithm based on traditional edge detection, this paper proposes a novel edge direction determination method. On the basic of the preliminary direction judgment obtained from the absolute difference, the reliability judgment of the direction is added. The correlation between the vertical direction of the current pixel and the pixel mean of the remaining four directions is used to obtain a direction determination criterion, and then interpolation is performed by means of median filtering. The experimental results indicate that the PSNR and visual quality of the proposed algorithm outperforms other existing methods, whether its objective evaluation or subjective evaluation.
