(color online) The distributions of ENL and P_[m,n] from 1500 sub-reconstructed images. (a) The object is dice. The black, red, green, blue, yellow, and magenta lines represent ENL, P_[0,10], P_[10,20], P_[20,30], P_[30,40], and P_[40,50], respectively. (b) The object is coin. The black, red, green, blue, yellow, and magenta lines represent ENL, P_[100,110], P_[110,120], P_[120,130], P_[130,140], and P_[140,150], respectively. The vertical axis has been quantified for better comparison.
