Abstract

são descritos um sistema e método para detecção da qualidade de uma imagem digital capturada representando um documento impresso. a imagem digital capturada é analisada para determinar um borrão, ruído, ponto de acesso correspondente e métrica de iluminação desigual que representa um nível de qualidade dos dados de imagem. o borrão, ruído, ponto de acesso, e métricas de iluminação desiguais são então combinados para formular a indicador de passagem/alerta/falha para o usuário responder à qualidade de imagem digital capturada.
