Patent ID: 10484621

Abstract:
Systems and methods for providing imaging content using spatially varying encoding quality. Imaging content may be acquired using spherical lenses (e.g., fisheye). When viewing spherical imaging content, spherical to planar image transformations may be utilized. Such transformations (e.g., equirectangular) may be characterized by spatially varying image distortion. Transformed images may be encoded. Encoding process may be configured based on spatially varying encoding quality. Encoding quality may be configured based on the transformation such that portions of the transformed image characterized by greater distortion may be encoded using lower quality (e.g. greater QP values); portions of the transformed image characterized by lower distortion may be encoded using greater quality (e.g. lower QP values). Such encoding may produce a bitstream characterized by a lower bitrate for a given quality and/or better quality for a given bitrate as compared to an encoding process that may apply a uniform encoding quality.
