Electro-Mechanical Model of the Human Visual System
Journal of the Optical Society of America, 1957A servomechanism is described which simulates the eye response in directing visual receptors. Feedback to provide corrective directing is based upon matching the images conducted to the “brain” by the neurons. The model uses photoelectric cells to receive the images. The image from each receptor unit (eye) is separated into two parts.

The Neuromorphic Model of the Human Visual System
2020The purpose of this work was to study the structure and operation of the human visual system, as well as its mathematical description and computer modeling. The work included the following stages: analysis of the structure and functioning of the visual system from a biological point of view; construction of a mathematical model of the retina ...

Area Summation in Human Visual System: Psychophysics, fMRI, and Modeling
Journal of Neurophysiology, 2009Contextual modulation is a fundamental feature of sensory processing, both on perceptual and on single-neuron level. When the diameter of a visual stimulus is increased, the firing rate of a cell typically first increases (summation field) and then decreases (surround field).

Modeling the critical fliker fusion frequency in the human visual system
Биофизика, 2023The temporal resolving power of the visual system is essential for the perception of the objective world. The lowest sampling rate of a sequence of images at which perception becomes fused is called the critical flicker fusion frequency. The variety of experimental data on critical frequency thresholds can be explained from a point of view of a model ...

An Interactive System for Visualizing 3D Human Organ Models
Ninth International Conference on Computer Aided Design and Computer Graphics (CAD-CG'05), 2006Demonstrations play a major role in education process. Although many specimens are readily available, particularly in medicine and biology, demonstrations are commonly performed by showing these static specimens to medical or biological students. Interactive demonstrations can significantly impacts learning.

A computational model for human visual motion perception system
IFAC Proceedings Volumes, 1999Abstract Reichardt's elementary motion detectors are employed for detecting motion. Moving image-stationary background discrimination is realized by correlating the detected motion information with properly delayed visual afterimages. Fuzzy-set theory is used in a nonlinear integration algorithm for obtaining a moving object direction.

Human Visual System and Vision Modeling
2018The computational modeling of human visual system (HVS) is closely connected with image quality assessment (IQA) since visual signal quality is always finally evaluated by the former. Therefore, basic knowledge about HVS, especially its parts that are in charge of quality perception, should be aware of for studying IQA.

Alpha stable human visual system models for digital halftoning
SPIE Proceedings, 2006Human visual system (HVS) modeling has become a critical component in the design of digital halftoning algorithms. Methods that exploit the characteristics of the HVS include the direct binary search (DBS) and optimized tone-dependent halftoning approaches.

Image invariances based on human visual system models
Annual Meeting Optical Society of America, 1986Studies of the human visual system have led to neural network models for computing with a variety of architectures and algorithms that can exploit invariants in image processing, feature extraction,1 and subsequently fault-tolerant associative memory for pattern recognition.
