Abstract: This research proposes an Adaptive Weighted Fuzzy Mean Filter (AWFMF) based on Cloud Model (CM) to remove the
salt and pepper noise in the digital images. Also, the performance of the
proposed filter is compared with existing variants of median and switching
filters using peak signal to noise ratio (PSNR) and quality index. The
proposed filter is able to remove salt and pepper noise even at 90% noise level
with good detail preservation.
Keywords: Image denoising, salt and pepper noise, CM.
