Deinterlacing using multi direction detection with fixed adaptive tap interpolation filter

Abstract

This paper proposes a multi directions detection deinterlacing algorithm using fixed adaptive tap interpolation filter. The proposed algorithm determines the multi directions of the interpolated pixel, to obtain more direction correlation pixels and use fixed coefficient filter for multi pixels interpolation. The proposed algorithm which adopts only direction correlation pixels can increase pixels correlation and improve visual quality. But multi directions detection costs a little more computation time. Experimental results demonstrate that the proposed algorithm outperforms the conventional deinterlacing methods.
