Abstract

"DISPOSITIVO MéTODO PARA CRIAR UM MAPA DE SALIêNCIA DE UMA IMAGEM". A invenção se relaciona com um dispositivo e método para criar um mapa de saliência de uma imagem. Ela compreende as etapas de: Projeção (E1) da dita imagem de acordo com o componente de luminância (A) e se a dita imagem for uma imagem colorida, de acordo com o componente de luminância (A) e de acordo com os componentes de crominância (Cr1, Cr2); decomposição em sub-bandas perceptivas (E3, T2, T<39>2, T<39><39> 2) dos ditos componentes (A, Cr1, Cr2) de acordo com o limite de visibilidade de um olho humano; Extração (E7) dos elementos salientes das sub-bandas relacionadas com o componente de luminância (A) ; Aprimoramento de contorno (E8, T7) dos ditos elementos salientes em cada sub-banda relacionada com o componente de luminância (A); Cálculo (T7) de um mapa de saliência a partir do aprimoramento de contorno, para cada sub-banda relacionada com o componente de luminância (A) . Criação (T8) do mapa de saliência em função dos mapas de saliência obtidos para cada sub-banda.
