Abstract

MÉTODOS IMPLEMENTADOS POR COMPUTADOR E DISPOSITIVOS PARA DETERMINAÇÃO DE DIMENSÕES E DISTÂNCIAS DE PARTICULARIDADES DA CABEÇA. A presente invenção refere-se a métodos implementados por computador e dispositivos para determinação de dimensões ou distâncias de particularidades da cabeça. O método inclui a identificação de uma pluralidade de particularidades em uma imagem da cabeça de uma pessoa. Uma dimensão real de pelo menos uma particularidade alvo da pluralidade de particularidades ou uma distância real entre pelo menos uma particularidade alvo da pluralidade de particularidades e um dispositivo de câmera usado para capturar a imagem é estimada com base em distribuições de probabilidade para dimensões reais de pelo menos uma particularidade da pluralidade de particularidades e uma dimensão de pixel de pelo menos uma particularidade da pluralidade de particularidades.
