摘要：In this paper, a novel adaptive loop filter model for video coding that predicts pixel values from local dithered binary patterns and a look-up table (LUT) is proposed. It can refine a decoded image adaptively to its local texture by using a LUT that is used in inverse halftoning techniques. The LUT is generated so that the sum of the improvements in the decoded image is maximized. Experimental results, in which the total bitrates including the LUT and PSNR were compared with the conventional method demonstrated the efficiency of the proposed method.
