An Algorithm for Simple and Complex Feature Detection: From Retina to Primary Visual Cortex
Abstract
This report describes a hierarchy of functions for the processing of visual motion and pattern information culminating in descriptive sets of features. Processing elements that model simple feature detectors respond maximally only when a stimulus grating pattern with a specific orientation and spatial period is located in phase with the center and surround of the element's receptive field. Processing elements that model complex feature detectors respond maximally only when a stimulus grating pattern with a specific orientation and spatial period is moved in a specific direction through the element's receptive field.... Center surround receptive fields, Motion selectivity, Log-polar mapping, Cortex, Thalamic LGN.
