Abstract
trata-se de um sistema de geração de tela que gera uma visão de tela de uma cena com base em um conjunto de visões de câmera originais retratando a cena, por exemplo, para recriar uma cena em realidade virtual. as visões de tela podem ser geradas com base em um conjunto de visões sintéticas geradas a partir de um conjunto de visões de câmera originais. as visões sintéticas podem ser geradas, por exemplo, pelo deslocamento e combinações de visões de câmera originais relevantes com base em um fluxo óptico ao longo de múltiplas visões de câmera originais. um fluxo óptico pode ser gerado usando um método iterativo que otimiza individualmente o vetor de fluxo óptico para cada pixel de uma visão de câmera e propaga alterações no fluxo óptico aos vetores de fluxo óptico adjacentes.
