WebbHDR radiance image reconstruction (Debevec’s algorithm) The goal of this stage is to estimate the radiance value at every scene point from a set of images that are taken from the same vatange point with different known exposure duration. Here, I used Debevec’s algorithm [1] to achieve this purpose.
