Adaptive filtering for image denoising
Angelo Bosco, Matilde Mancuso · 2002
This paper presents an adaptive image filter that reduces the amount of noise in images acquired by digital still camera sensors in a Bayer pattern format. The filter acts mainly on the high spatial frequency components of the image in all the areas where they are not perceived by the human visual system (HVS); thus it is an adaptive filter that improves the image quality.
