Abstract
An image recognition and classification system includes a preprocessor in which a 'top-down' method is used to extract features from an image; an associative learning neural network system, which groups the features into patterns and classifies the patterns: and a feedback mechanism which improves system performance by tuning preprocessor scale, feature detection, and feature selection.
