Fig. 3From: Low-light image restoration using bright channel prior-based variational Retinex modelExperimental results using various sets of regularization parameters: a input image; b simulated low-light image; c resulting image with λ 1=300, λ 2=0.1, λ 3=0.9, and ω=10; d resulting image set with different λ 1; e resulting image set with different λ 2; and f resulting image set with different λ 3 Back to article page
