Abstract

Performances of some image restoration filters are compared and evaluated on SNR gain and subjective test. Test images used here are the GIRL and PLANT images corrupted by Gaussian, uniform, BSC, and impulse noise, respectively. Experimental results show that the scalar DCT-Wiener filter among them is comparatively superior to others in Gaussian and uniform noise. On the other hand, the median filter is much better than others in BSC and impulse noise.
