Image denoising involves processing of the image data to produce a visually high quality image. The denoising algorithms may be classified into two categories, spatial filtering algorithms (Wiener filter, Gaussian filter, Gabor filter and Median filter) and wavelet based algorithms (Wiener filter in the wavelet domain and Log Gabor filter in the wavelet domain). In this paper a comparative study for the previous mentioned algorithms based on calculating the Peak Signal to Noise Ratio (PSNR) value as a metric since for such images the visual evaluation is not appropriate. The quantitative results of comparison are tabulated by calculating the PSNR of the output image.

Abstract


Image denoising involves processing of the image data to produce a visually high quality image. The denoising algorithms may be classified into two categories, spatial filtering algorithms (Wiener filter, Gaussian filter, Gabor filter and Median filter) and wavelet based algorithms (Wiener filter in the wavelet domain and Log Gabor filter in the wavelet domain). In this paper a comparative study for the previous mentioned algorithms based on calculating the Peak Signal to Noise Ratio (PSNR) value as a metric since for such images the visual evaluation is not appropriate. The quantitative results of comparison are tabulated by calculating the PSNR of the output image.
