概要
- 論文の詳細を見る
A modified Wiener filtering method is proposed for resolution enhancement without any loss of the peak signal-to-noise ratio (PSNR), whereby the filtering strength applied to the edge region is adjusted using a modified filter kernel. In spite of the increased filtering strength in the edge region, strong edges are still preserved. Compared to the conventional Wiener filter, the modified Wiener filter provides higher PSNR and better subjective image quality in the filtered image.
