Abstract
Sharpness enhancement is widely used technique for improving the perceptual quality of an image by emphasizing its high-frequency component. In this paper, a psychophysical experiment is conducted by the 20 observers with simple linear unsharp masking for sharpness enhancement. The experimental result is extracted using z-score analysis and linear regression. Finally using this result we suggest observer preferable sharpness enhancement method for digital television.
