The challenge solicited solutions that processed RAW camera images captured in night scenes to produce a photo-finished output image encoded in the standard RGB (sRGB) space.

We present a three-dimensional generalization of linear Hough transform allowing fast calculating of sums along all planes in discretized space. The main idea of this method is multiple calculation of two-dimensional fast Hough transforms combined with a specific method for plane parametrization

A simple convolutional neural network was able to win the ISISPA color constancy competition. Partial reimplementation of the neural architecture from would have shown even better results in this setup.

This work is devoted to the theoretical substantiation of various properties of spectral models. In particular, we prove that the banded model is the only model that simultaneously possesses the properties of closure under addition and multiplication. We also show that the Gaussian model is the limiting case of the von Mises model and prove that the von Mises model unambiguously covers the color triangle in cases of both convex and non-convex spectral loci.
