This paper presents an adaptive interpolation algorithm for effective picture format conversion, namely deinterlacing based on total edge directions estimation. The deinterlacing algorithms are generally made up of two parts, such as the estimation of edge directions and the interpolation of missing pixels along with the estimated direction. The proposed algorithm adopts and enhances the block-based search concept for estimation of edge directions, which is introduced in the direction-oriented interpolation (DOI) algorithm. In this paper the edge directions are estimated with the vertical angles as well as the horizontal angles in the DOI and then the missing pixels are interpolated by using median operation. Experimental results show that the proposed algorithm can estimate edge directions and interpolate missing pixels more accurately compared with the conventional deinterlacing algorithms in terms of the objective performance measured in PSNR and the subjective visual quality.
