A rank-ordered marginal filter for deinterlacing

This paper proposes a new interpolation filter for deinterlacing, which is achievedby enhancing the edge preserving ability of the conventional edge-based line averagemethods. This filter consists of three steps: pre-processing step, fuzzy metric-based weightassignation step, and rank-ordered marginal filter step. The proposed method is able tointerpolate the missing lines without introducing annoying articles. Simulation results showthat the images filtered with the proposed algorithm restrain less annoying pixels than theones acquired by other methods.
