Gradient Domain HDR Compression

Here we show HDR compression results produced using gradient domain image compression [Fattal et al. 2002].

The result on the left was obtained using a Poisson solver with von Neumann boundary conditions, while that on the right uses our method. In both cases, we used the same post-processing, which consists of stretching the result so 0.5% of the pixels are dark-clipped.
