    • Innovations in flexible reference picture management are described. For example, a video encoder and video decoder use a global reference picture set ("GRPS") of reference pictures that remain in memory, and hence are available for use in video encoding/decoding, longer than conventional reference pictures. In particular, reference pictures of the GRPS remain available across random access boundaries. Or, as another example, a video encoder and video decoder clip a reference picture so that useful regions of the reference picture are retained in memory, while unhelpful or redundant regions of the reference picture are discarded. Reference picture clipping can reduce the amount of memory needed to store reference pictures or improve the utilization of available memory by providing better options for motion compensation. Or, as still another example, a video encoder and video decoder filter a reference picture to remove random noise (e.g., capture noise due to camera imperfections during capture).
    • 描述了灵活的参考图片管理的创新。 例如,视频编码器和视频解码器使用保留在存储器中的参考图片的全局参考图片集(“GRPS”),并且因此可用于视频编码/解码,比传统参考图片更长。 具体而言,GRPS的参考图片在随机访问边界上保持可用。 或者,作为另一示例,视频编码器和视频解码器剪切参考图片,使得参考图片的有用区域被保留在存储器中,而参考图片的无用或冗余区域被丢弃。 参考图片裁剪可以减少存储参考图片所需的内存量,或通过提供更好的运动补偿选项来提高可用内存的利用率。 或者,作为又一示例,视频编码器和视频解码器对参考图片进行滤波以去除随机噪声(例如,捕获期间由于相机瑕疵造成的捕获噪声)。
