In this paper, we propose a new vertical temporal filtering method for deinterlacing, which utilizes correlations between adjacent frames. In this model, we first compute differences between the current frame and adjacent frames. Since the differences between adjacent frames would show similar patterns, we exploit this similarity for improved deinterlacing results. The proposed method has low complexity and still produces superior performance. Experimental results show that the proposed method provides noticeable improvements over existing methods in terms of both subjective and objective evaluations.
