Fig. 1From: Multiplicative noise removal using primal–dual and reweighted alternating minimizationExperimental results on Shape1 image (multiplicative noise with standard variance 1/10). a Original image; b noisy image; c denoised image by SO (SNR = 7.9142 dB); d denoised image by HNW (SNR = 9.2177 dB); e denoised image by classic iteratively reweighted algorithm (SNR = 12.3661 dB); f denoised image by our algorithm (SNR = 12.3856 dB)Back to article page
