Abstract

This paper proposes a spatial domain deinterlacing method which is based on fuzzy rule and edge-sensitive line average algorithm. The proposed algorithm consists two parts: edge direction detection part and fuzzy rule based edge-sensitive interpolation part. Once the edge direction is determined, in order to accurately reconstruct boundary of edges and peaks, edge-sensitive interpolation is utilized. Detection and interpolation results are presented. Experimental results show that the proposed algorithm provides a significant improvement over other existing deinterlacing methods.
