Observer Preferable Sharpness Enhancement Considering Distributions of Edge Characteristics

경계선 특성을 고려한 관측자 선호 선예도 개선 방법

Sharpness enhancement, which strengthen the edge(high frequency) of image, is widely studied for image processing research area. In this paper, psychophysical experiment is conducted by the 20 observers with simple linear unsharp masking for sharpness enhancement. The experimental results extracted using z-score analysis and linear regression suggests observer preferable sharpness enhancement method for digital television.
