PRT-inspired hybrid neural-wavelet architectures trained on images can learn a scene's global illumination light transport tensor. Decoupling relighting from scene information as well as prediction in an orthonormal basis enable generalization to novel view and novel lighting conditions for many complex effects, such as rotating caustics.

Modeling The Effect of Lateral Inhibition in the Retina on Color Perception
CS 294-164: A biologically-plausible model for fixational drift motion in the retina based on Anderson, et al. (2020) taking into account neuronal lateral inhibition is able to better reconstruct higher-contrast regions of input stimuli, and could potentially show more improvements with a well-chosen spatial prior
