Abstract

A presente invenção se refere a um processamento de vídeo para análise de tarefas motoras. Em vários exemplos, um vídeo de pelo menos uma parte de uma pessoa ou animal executando uma tarefa motora, tal como colocando o dedo indicador sobre o nariz, é enviado para um sistema de aprendizado de máquina treinada para classificar a tarefa motora em uma dentre uma pluralidade de classes. Em um exemplo, descritores de movimento, tais como um fluxo óptico, são calculados a partir de pares de quadros de vídeo, e os descritores de movimento são enviados para o sistema de aprendizado de máquina. Por exemplo, durante o treinamento, o sistema de aprendizado de máquina identifica características de aceleração ou velocidade dependentes de posição e/ou dependentes do tempo, características essas que discriminam entre classes de tarefas motoras. Nos exemplos, o sistema de aprendizado de máquina treinada calcula, a partir dos descritores de movimento, as características de aceleração ou velocidade que aprendeu como sendo bons discriminadores. Em vários exemplos, uma característica é calculada usando subvolumes do vídeo.
