Rate-Distortion Optimized Motion Estimation for on-the-Sphere Compression of 360 Videos

On-the-sphere compression of omnidirectional videos is a very promising approach. First, it saves computational complexity as it avoids to project the sphere onto a 2D map, as classically done. Second, and more importantly, it allows to achieve a better rate-distortion tradeoff, since neither the vi…
