Abstract

"SUBSTITUIçãO DO COMPONENTE CINZA NEUTRO-ILUMINADOR EM SISTEMAS PARA MULTIPLEXAçãO ESPECTRAL DE IMAGENS FONTES PARA PROPORCIONAR UMA IMAGEM COMPOSTA, PARA GERAçãO DA IMAGEM COMPOSTA E PARA DEMULTIPLEXAçãO ESPECTRAL DA IMAGEM COMPOSTA". A presente invenção refere-se a métodos e aparelhos para codificar espectralmente, imagens fontes plurais e para fornecer as imagens fontes plurais codificadas espectralmente em uma imagem composta, para gerar a imagem composta em uma forma física ou para recuperar pelo menos uma dentre as imagens fontes codificadas da imagem composta gerada, tal que a imagem fonte recuperada se torne distinguível. A confusão da imagem fonte em uma imagem composta gerada é controlada por meio da aplicação de uma técnica de substituição de componente cinza neutro-iluminador (GCR) ao obscurecimento comum aos diferentes colorantes sob os múltiplos iluminadores.
