Abstract

método e sistema para detecção de vivacidade facial baseada em crominância. a presente invenção refere-se a métodos, sistemas e meio legível por computador para autenticação de detecção de vivacidade de uma imagem facial. o método inclui adquirir uma primeira imagem da imagem facial iluminada com uma primeira cor, adquirir uma segunda imagem da imagem facial iluminada com uma segunda cor, e determinar se a imagem facial é consistente com uma estrutura tridimensional (3d) em resposta a uma combinação das primeira e segunda imagens. o método ainda inclui autenticar a imagem facial se a imagem facial for consistente com uma estrutura 3d e a imagem facial corresponder à face de um usuário a ser autenticado.
