Redes Neurais Baseadas em Regiões Perceptivas para o Reconhecimento de Caracteres Manuscritos

Simone B. K. AiresCinthia O. A. FreitasFlavio BortolozziJúlio C. Nievola

This work investigates the perceptual zoning mechanism for handwritten character recognition and proposes a non-symmetrical zoning mechanism as the baseline feature extractor. Zoning is a method for local information analysis on partitions of a given pattern. The feature extraction is based on Concavities/Convexities, circumscribing the letter by a rectangle and partitioning it into Z parts, say Z = 4, 5H (Horizontal), 5V (Vertical), and 7. For the recognition problem a Neural Network committee is used.
