Abstract

There are several approaches to texture analysis and classification. Most have limitations in accurate discrimination or complexity in time calculation. A first phase is the extraction of texture features and later we classify it. Texture features should have the followings properties: be invariant under the transformations of translation, rotation, and scaling; a good discriminating power; and take the non-stationary nature of texture account. In Our approach we use Orthogonal Associative Neural Networks to Texture identification. It is used in the feature extraction and classification phase (where its energy function is minimized). Due his low computational cost and his regular computational structure the implementation of a real-time texture classifier based on this algorithm is feasible. There are several platforms to implement Artificial Neural Networks (VLSI chips, PC accelerator cards, multiboard computers, ...). The election relies on the type of neural model, their application, the response time, capacity of storage, type of communications, and so on. In this paper we present a pipeline architecture, where precision, cost and speed are optimally trade off. In addition we propose CPLD (Complex Programmable Logic Device) chips to complete realization of the system. CPLD chips have a reasonable density and performance at low cost.
