Image Enhancement under Data-Dependent Multiplicative Gamma Noise

Figure 1

Images restored using various methods, images of “peppers”: (a) and (e): noisy images with mean 1, noise variances 0.1 and 0.2, and Gaussian blurs with kernel spread of 3 & 4, respectively; (b) and (f) restored using RLO method [10]; (c) and (g) restored using AA filter [8]; (d) and (h) restored using the proposed method.
