Abstract

"MéTODO E APARELHO PARA INSPECIONAR UMA FOLHA CONTìNUA". Um método para inspecionar uma folha contínua móvel. O método inclui formar imagem de uma parte seqüencial da folha que se move continuamente, para fornecer informação digital. A informação digital é então processada com um algoritmo inicial, para identificar quaisquer regiões da folha contínua contendo anomalias. A informação de imagem, correspondente a qualquer região identificada dentro da informação digital, é então selecionada. A informação de imagem selecionada é então analisada com pelo menos um subseqüente algoritmo, para distinguir defeitos reais entre as anomalias.
