Abstract

DETECçãO DE ESTADO DE COR EM DOMìNIO BINáRIO DE COR. Refere-se a um método para determinar o estado de cor de um original escaneado segmenta uma imagem binária de meio-tom em um número predeterminado de janelas locais e converte cada janela local em um espaço de cor independente de dispositivo. O método, então, determina um parâmetro de espaço de cor para cada janela local e compara os parâmetros de espaços de cor para as janelas locais com pelo menos um limite para determinar o estado de cor do original escaneado. Um aparelho tendo um scanner cria uma imagem escaneada de um original e tem pelo menos um processador para criar um imagem binária de meio-tom da imagem escaneada, segmentar a imagem binária de meio-tom em um número predeterminado de janelas locais, converter cada janela local em um espaço de cor independente de dispositivo, determinar um parâmetro de espaço de cor para cada janela local e comparar o parâmetro de espaço de cor para cada janela local com pelo menos um limite para determinar o estado de cor para o original escaneado.
