Desarrollo de un sistema prototipo de reconocimiento de dígitos usando momentos invariantes

Abstract

Este proyecto propone una alternativa para asistir a las personas invidentes en la lectura de documentos impresos usando un celular inteligente con cámara fotográfica. A lo largo del documento se muestran los algoritmos utilizados para procesar las imágenes, extraer características de las imágenes y clasificarlas para hacer reconocimiento óptico de dígitos numéricos. También se exponen los retos planteados por el problema y las soluciones que se propusieron para lograr una buena tasa de reconocimiento. Finalmente se analizan los resultados obtenidos por los diferentes algoritmos implementados para el reconocimiento de dígitos, y se muestra la flexibilidad y escalabilidad del sistema, al incluir reconocimiento de los caracteres del alfabeto latino en mayúsculas. Se analizan los resultados del reconocimiento óptico de caracteres y se plantean proyectos futuros para agregar la funcionalidad requerida por las personas invidentes.
