Figure 17From: Realistic camera noise modeling with application to improved HDR synthesisComparison of different weighting functions in the Δ SNR sense (difference in SNR compared to the triangular function of Debevec and Malik) for γ ( z )= z . The SNR was computed using (24) and in (a) averaged as function of the gain α, in (b) averaged as function of the offset noise standard deviation σ o .Back to article page
