Abstract

método, sistema e pelo menos uma mídia legível por máquina. trata-se de técnicas relacionadas à codificação de vídeo imersivo, incluindo múltiplas texturas e visualizações de profundidade de uma cena. tais técnicas incluem a redução da profundidade de bits de uma vista de profundidade com o uso de um mapeamento linear por partes antes de codificar, mapeamento inverso de uma vista de profundidade decodificada de baixa profundidade de bits para a profundidade de bits alta com o uso do mapeamento linear por partes e codificação e decodificação eficiente de parâmetros de câmera correspondentes ao vídeo imersivo.method, system and at least one machine-readable medium. These are techniques related to immersive video coding, including multiple textures and depth views of a scene. Such techniques include reducing the bit depth of a depth view using a piecewise linear mapping before encoding, inversely mapping a decoded depth view from low bit depth to high bit depth using the piecewise linear mapping and efficient encoding and decoding of camera parameters corresponding to immersive video.
