Abstract

"SISTEMAS E MéTODOS PARA ESTIMATIVA DE PROCESSO DE MARCAçãO DE IMAGEM USANDO ATRIBUTOS DE IMAGEM DIGITALIZADA". Métodos e sistemas usados para identificar automaticamente o processo de marcação usado para uma imagem em um substrato com base nas características espaciais elou cor da imagem. Tipos de imagem que são classificados e identificados incluem imagens de tons contínuos e imagens de meios-tons. Entre imagens de meios-tons identificadas separadamente estão imagens em jato de tinta, imagens xerográficas e imagens litográficas. Técnicas de limite de imagem localmente adaptativas podem ser usadas para determinar as características espaciais da imagem.
