Abstract

determinação de informação de cor, usando um sensor binário. a invneção refere-se á formação de uma imagem utilizando píxeis binários. píxeis binários são píxeis que possuem apenas dois estados, um estado branco quando o pixel está exposto e um estado preto quando o pixel não está exposto. os píxeis binários têm filtros de cores em cima deles, e a configuração de filtros de cor pode ser conhecida em algum grau. uma configuração fazendo uso de uma abordagem estatística pode ser usada para determinar a cor da luz de entrada para produzir imagens de saída. por conseguinte, a abordagem pode ser utilizada com a matriz de píxeis binários para produzir imagens a partir das imagens de entrada que a matriz de píxeis binários registra.
