Visual perception¶
The perception
module of odak
focuses on visual perception, and in particular on gaze-contingent perceptual loss functions.
Metamers¶
It contains an implementation of a metameric loss function. When used in optimisation tasks, this loss function enforces the optimised image to be a ventral metamer to the ground truth image.
This loss function is based on previous work on fast metamer generation. It uses the same statistical model and many of the same acceleration techniques (e.g. MIP map sampling) to enable the metameric loss to run efficiently.
