Human Texture Vision as Multi-Order Spectral Analysis

Texture information plays a critical role in the rapid perception of scenes, objects, and materials.Here, we propose a novel model in which visual caruso rhodiola texture perception is essentially determined by the 1st-order (2D-luminance) and 2nd-order (4D-energy) spectra.This model is an extension of the dimensionality of the Filter-Rectify-Filter (FRF) model, and it also corresponds to the frequency representation of the Portilla-Simoncelli (PS) statistics.

We show that preserving two spectra and randomizing phases of a natural texture image result in a perceptually similar texture, strongly supporting the model.Based on only two single spectral spaces, this model provides a simpler framework to describe and predict texture representations in the primate visual system.The idea of multi-order spectral analysis is consistent with the hierarchical processing 6-0 igora vibrance principle of the visual cortex, which is approximated by a multi-layer convolutional network.
