To this end, a deep learning based 360 degree video codec will be built to distill the spatiotemporal characteristics of video features and optimize both compression ratio and analytics accuracy. Second, an adaptive 360 degree video bitrate streaming system will be designed to ensure continuous delivery of full 360 degree video frames by prioritizing regions of interest preferred by machines. Third, a 360 degree video recovery scheme will be developed to restore noisy and delayed video data while considering the time constraints in the online analytics.
