Visual pattern recognition in humans
Biological Cybernetics, 1987We have investigated how observers learn to classify compound Gabor signals as a function of their differentiating frequency components. Performance appears to be consistent with decision processes based upon the least squares minimum distance classifier (LSMDC) operating over a cartesian feature space consisting of the real (even) and imaginary (odd ...

Visual pattern recognition using morphological methods
[Proceedings] ICASSP-92: 1992 IEEE International Conference on Acoustics, Speech, and Signal Processing, 1992An effective method for visual pattern recognition using morphological techniques is presented. It is shown that it can be successfully used for the recognition of deformed letters. The method extracts morphological information by the successive dilation of an idealized letter set. At each stage a properly defined similarity index is computed.

Visual pattern based object recognition system
Proceedings of 1995 IEEE International Conference on Fuzzy Systems. The International Joint Conference of the Fourth IEEE International Conference on Fuzzy Systems and The Second International Fuzzy Engineering Symposium, 2002We investigate a knowledge model for our previously proposed approach to object recognition based on low level pattern features (W. Zhang and A. Ralescu, 1994). This knowledge includes rules which can deal with situations in which an object may be occluded.

Visualizing Neural Networks for Pattern Recognition
Proceedings of the International Conference on Pattern Recognition and Artificial Intelligence, 2018Understanding how a machine learns is a pressing topic as machine learning becomes more complex enabled by more powerful computers. This paper presents a visualization of neural networks to make them trackable during the operation of learning for pattern recognition, as well as testing for patterns.

Recognition of visual pattern components in squirrel monkeys
European Archives of Psychiatry and Neurological Sciences, 1986In 4 mixed-age captive groups of squirrel monkeys the predator alarm behavior control by means of visual stimuli was studied, and the extent to which socially inexperienced infant squirrel monkeys are capable of species-specific alarm behavior. By means of color film projection it was shown that both the socially experienced and inexperienced subjects ...

Visual Pattern Recognition: Size Preprocessing Re-Examined
The Quarterly Journal of Experimental Psychology Section A, 1983Template theories of visual pattern recognition assume the operation of preprocessing routines to deal with irrelevancies such as discrepancies in stimulus size. In three experiments where size was an irrelevant dimension, observers classified pairs of forms as either “same” or “different”.

Pattern Recognition with the Optic Nerve Visual Prosthesis
Artificial Organs, 2003Abstract: A volunteer with retinitis pigmentosa and no residual vision was chronically implanted with an optic nerve electrode connected to an implanted neurostimulator and antenna. An external controller with telemetry was used for electrical activation of the nerve which resulted in phosphene perception.

Visual pattern recognition in Drosophila involves retinotopic matching
Nature, 1993Honeybees remember the shapes of flowers and are guided by visual landmarks on their foraging trips. How insects recognize visual patterns is poorly understood. Experiments suggest that they try to match retinotopically the incoming visual pattern with a previously stored memory image.

Light adaptation for visual pattern recognition in flies
Vision Research, 1973Abstract Flies were found to possess the light adaptation phenomena of vertebrates whereby the eyes achieve optimal sensitivity to an intensity increment on a given background illumination. This was found in the photoreceptors and several higher levels including a behavioral response.

Visual Pattern Recognition in Animals
1971Some two thousand million years ago living organisms initiated the invention of means for detecting optical signals to be reacted to by purposeful actions. This decisive evolutionary step already took place at the primitive organizational level of the bacteria, as may be inferred from present life.
