Abstract:

To optimize coding efficiency, an encoder minimizes total distortion under a constraint rate. Distortion criteria for conventional video uniformly measures coding error around picture. For non-equal area projection formats of 360 video, e.g., equirectangular projection (ERP), cube map projection (CMP), uniformly measured distortion cannot...More
