Psychology Definition of FEATURE DETECTION THEORY: a theory that states that all complex stimuli are able to be broken down into individual parts or features each of which is then analysed by a feature dete
Feature detection is a process in which the brain detects specific elements of visuals, such as lines, edges or movement. Nerve cells respond to the specific details and hone in on selective shapes and lights, thus blurring out the larger image.
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.
feature detection theory. Quick Reference. Any of a number of theories according to which the perception of objects proceeds by recognizing individual features (1), such as a pair of wheels, a pair of pedals, a handlebar, a saddle, and an M-shaped metal frame, and assembling them to form a coherent pattern, in this example a bicycle, which is ...
A theory of perception that proposes the existence of feature detectors, cortical cells that fire only when we see certain visual stimuli such as shapes, colors of light or movement.
Feature Detection I think is just when you detect certain features of a stimuli (e.g. colour, motion, etc.) but this is always when you detect a stimulus, contrary to signal Detection Theory when you don't always detect it correctly. I think this is the jist of it, hopefully someone else can confirm/correct me if this explanation wasn't the best :p
Feature detection: the Feature Detection Theory describes why a particular part of our brain is triggered when we look at something (ie. looking at animals trigger one part of the brain, and looking at words trigger a different part.) Hearing. Structure and function of the ear ear structure Ear canal = auditory canal.
In this video, I review our ability to break down an image into its component "features" such as color, form, and motion. This is known as feature detection, and since the detection of various features happens simultaneously, or in parallel, it is referred to as parallel processing. By Ronald Sahyouni.
In Feature Integration Theory Combine features: combine "what" and "where" processes Puts together basic features to perceive object Creates higher attentional demand (comes after feature detection)
2) Objects = combination of features 3) Features = Small (local) templates that can be combined in many different ways to form different objects. 4) We recognize the features, then recognize the combination 5) Two feature analysis theories: -Pandemonium-Recognition by Components (RBC) (Geon Theory)
