Feature detection is a process by which the nervous system sorts or filters complex natural stimuli in order to extract behaviorally relevant cues that have a high probability of being associated with important objects or organisms in their environment, as opposed to irrelevant background or noise.

WebMar 9, 2024 · Feature detectors are neurons in the brain that respond to specific aspects of a stimulus. These stimulus are; Edges, Lines, Angles and Movements. Feature detectors in the visual cortex are responsible for sending signals to other areas of the cortex for higher-level processing. WebHubel & Wiesel's description of simple cells as linear with bar- or edge-shaped receptive fields led to a view of the cortex as containing a population of feature detectors (Barlow I969, p. 881) tuned to edges and bars of various widths and orientations.
