From: Unsupervised estimation of signal-dependent CCD camera noise
Tests with simulated signal-dependent noise on a piecewise-smooth test image. Estimated (solid) and true (dashed) parameters of the photon (slope of regression line) and electronic (intercept) noise model as a function of true SNR. (a) Slope of the proposed method; (b) slope of the method in[5]; (c) intercept of the proposed method; (d) intercept of the method in[5]; (e) SNR of the proposed method; (f) SNR of the method in[5].
