Abstract

COMPRESSÃO DE VÍDEO USANDO SISTEMAS DE APRENDIZADO DE MÁQUINA DE BASE RECORRENTE. A presente invenção refere-se a técnicas que são descritas neste documento para codificar conteúdo de vídeo usando ferramentas de aprendizado de máquina de base recorrente. Um dispositivo pode incluir um sistema de rede neural incluindo porções do codificador e do decodificado. A porção do codificador pode gerar dados de saída para a etapa de tempo atual de operação do sistema de rede neural com base em um quadro de vídeo de entrada para uma etapa de tempo atual de operação do sistema de rede neural, dados de estimação de movimento reconstruídos a partir de uma etapa de tempo anterior de operação, dados residuais reconstruídos a partir da etapa de tempo de operação anterior e dados de estado recorrente a partir de pelo menos uma camada recorrente de uma porção do decodificador do sistema de rede neural a partir da etapa de tempo de operação anterior. Uma porção do decodificador do sistema de rede neural pode gerar, com base nos dados de saída e dados de estado recorrentes a partir da etapa de tempo anterior de operação, um quadro de vídeo reconstruído para a etapa de tempo atual de operação.
