Figure 3From: Realistic camera noise modeling with application to improved HDR synthesisIllustration of the recovery of irradiance values from a set of LDR images. (a) Inverse CRF compensated pixel intensities g(z ij ) as a function of the image irradiance E i , for three LDR photographs taken with different exposure times. (b) Recovering an image with a HDR by subtracting the offsets log Δ t j / Δ t j ′ (here, j′ = 2).Back to article page
