Glare Encoding of High Dynamic Range Images Supplemental Material

In our paper, we introduced a low energy, high frequency, shift variant component ρ̂ of the light transport function H, that captures cross-screen filter diffraction effects rS present in the captured image. In this section, we derive statistical properties of this function rS which we use in our paper (Equation 9 in the paper). First, we present empirical properties of derivatives of ρ̂ , and then relate them to derivatives of rS.
