In this paper, fuzzy condition rules are studied to improve video format conversion. The propose method consists of three parts: (1) system consideration, (2) image quality assessment, and (3) adjusting parameters. By adopting hedges in membership function, we apply additional effects for fuzzy operations. In addition, by providing condition rules for four fuzzy sets ‘fast’, ‘slow’, ‘homogeneity’, and ‘heterogeneity’, we could improve restored images. The hedges are applied in each fuzzy set depending on the input values, which provides additional effect. Experimental results show that the proposed method outperforms two benchmark methods.
