Interference filters as nonlinear decision-making elements for three-spot pattern recognition and associative memories.
Simple patterns consisting of three spots (V and Gamma) have been recognized by dividing, shifting, and recombining beams onto bistable ZnS interference filters. This experiment demonstrates AND-gate operation, cascading, and a moderate amount of parallelism, but a laser power of several watts was required and the response times were several milliseconds. An associative memory for fingerprint i...
متن کاملInvariant pattern recognition using analog recurrent associative memories
A novel invariant pattern recognition approach is proposed based on a special gradient-type recurrent analog associative memory. The system exhibits stable equilibrium points in predefined positions specified by feature vectors extracted from the training set, while invariance to geometrical transformations is inferred by using the tangent distance. Experimental results for handwritten characte...
متن کاملAssociative Memories Network for Face Recognition and Object Recognition
An associative memory (AM) is a special kind of neural network that allows associating an output pattern with an input pattern. Some problems require associating several output patterns with a unique pattern. Classical associative and neural models cannot solve this simple task and less if these patterns are complex images, for example faces. In this paper a network of AMs to recall a collectio...
متن کاملA pattern recognition account of decision making.
In the domain of pattern recognition, experiments have shown that perceivers integrate multiple sources of information in an optimal manner. In contrast, other research has been interpreted to mean that decision making is nonoptimal. As an example, Tversky and Kahneman (1983) have shown that subjects commit a conjunction fallacy because they judge it more likely that a fictitious person named L...
متن کاملAdaptive Median and Wiener Filters as Reference Functions for Morphological Associative Memories in Complete Inf-Semilattices
Mathematical morphology (MM) is a theory for nonlinear image and signal processing that was originally based on complete lattices and is usually still conducted in this framework. Later, MM was extended from complete lattices to complete inf-semilattices (cisls) using reference functions. Recently an auto-associative memory model based on a cisl was introduced by Sussner and Medeiros who conduc...
