The necessary contrast to provoke a response from the neurons is defined as the detection threshold. The inverse of the detection threshold is the contrast sensitivity. Contrast sensitivity varies with frequency (including spatial frequency, temporal frequency, and orientation) and can be measured using...
A feature, or descriptor, is defined as a function of one or more measurements, specifying some quantifiable property (ie, color, texture, or shape) of the whole image or subimage or of a single object. Many different methods for managing texture have been developed that are based on the ...
Keywords: Category Perceptual Unitization Learning, Perceptual Learning, Introduction Recent successful computational models in the categorization literature have represented objects as an arrangement of a set of features (Kruschke, 1992; Love, Medin, & Gureckis, 2004; Nosofsky, 1986; Spratling & ...
The proposed shape descriptor is based on the beams originated from a boundary point, which are defined as lines connecting that point with the rest of the points on the boundary. At each point, the angle between a pair of beams is calculated to extract the topological structure of the bound...
and perceptual experience are connected. As a form of enactivism, the sensorimotor approach largely rejects the idea that perception is an internal process of producing inner mental representations. Instead, perception is a process of interaction with and within the environment. Furthermore, it stresses...
1. Critically, the more sensitive approach of full psychometric curves revealed that perceptual saccadic suppression was much stronger for coarse than fine textures at peak suppression; that is, perceptual thresholds (defined as luminance increments required for a specific correct performance level; ...
of multiple feature dimensions, that is, information integration23. While these findings may seem at odds with results from single-unit recordings in monkeys, it is possible that the contribution of visual cortex to category learning depends on rather subtle changes in a restricted set of neurons....
aGestalt laws of organization:A set of rules describing the circumstances under which marks will be grouped into perceptual units, such as proximity,good continuation,similarity,closure,and good form. 组织形态法律:描述标记将被编组入感知单位,例如接近度,好继续、相似性、关闭和好形式的情况的规则组。[...
The main contributions of the paper are as follows: A Perceptual Hash Secure Storage and Transmission Framework (PH-SSTF) is designed to realize the secure storage and transmission of the original perceptual hash values by innovatively combining the private IPFS network and Hyperledger Fabric. This ...
A set of new binaural reverberation algorithms adapted from the Schroeder and Moorer reverberation algorithms are presented as well, with a linear structure that is simpler than the topology of Dattoro [9] and the feedback matrix structure of Alary [10]. The input audio enters through an FIR ...
