Comparing our method with a state-of-the-art single image denoising [Dabov et al.] and its extension to video denoising [Dabov et al.] on real image noise.

The images are captured using Pointgrey Dragonfly Express at its highest gain setting.

The camera moves along a linear rail and stops at 25 locations. The ground truth images are captured at the lowest gain setting at the same locations.
