In this paper, a direction-oriented covariance based deinterlacing method is presented. First, the local direction of edge is determined by modified edge-based line average (MELA) method. Then, based on the geometric duality, the optimal interpolation coefficients for the neighbor pixels of corresponding direction are estimated using the Wiener filtering. Experimental results prove that the proposed...
The adaptive weighting based on the intensity variations of the neighbor pixels and the distance between the neighbor pixels and a pixel to be interpolated is proposed for the edge-based deinterlacing method. The local edge direction is first determined by the modified edge-based line averaging (MELA) method. Then, according to the local edge direction, the inverse distance and intensity variation...
Nowadays the deinterlacing algorithm is using for converting the interlaced scan to progressive scan in HDTV system. The reason that the deinterlacing algorithm is necessity for this system is to prevent the serious distortion like flickering in fast motion. This paper presents an efficient deinterlacing algorithm that uses Wiener filter to detect the reliable direction of edge. With this algorithm...
