Description:
Visual perception gives us a reliable estimate of the world throughout the day, thanks to the computations implemented in visual circuits. In a given space or time, the relative change in luminance, contrast, forms the basis for many downstream computations like the detection of edges, shape, orientation and motion. Stable contrast estimation is challenged by the immensely changing lightning conditions that can slowly change throughout the day or much more rapidly when viewing natural scenes. To ensure reliable behavioral responses to the same (contrast) stimulus, visual systems face the mo...
