Abstract

a presente invenção refere-se a método implementado por computador, que inclui detectar, por um dispositivo de imagem, a presença de um objeto a ser representado por imagem. o método inclui ainda, de medida, pelo dispositivo de imagiologia, uma primeira propriedade do objeto a ser representado por imagem, e medição, pelo dispositivo de imagiologia, uma segunda propriedade do objeto a ser representado por imagem. o método ainda inclui a determinação, por um dispositivo de computação, que pelo menos uma da primeira propriedade do objeto ou a segunda propriedade do objeto excede um limiar; e em resposta à determinação, indicando, pelo dispositivo de computação, se o objeto a ser representado por imagem é um de um objeto falsificado ou um objeto real.
