Abstract

MéTODO DE SIMULAçãO DE GRANULAçãO DE FILME. Resumidamente, de acordo com uma concretização preferida dos presentes princípios, a simulação de um bloco de granulação de filme para adição a um bloco de uma imagem ocorre por estabelecer, primeiramente, pelo menos um parâmetro de imagem de acordo com pelo menos um atributo do bloco. Em seguida, um bloco de granulação de filme é estabelecido de acordo com o parâmetro de imagem. Pode-se aplicar filtragem por desagrupamento ao bloco de granulação de filme.
