Research Type Experimental Our empirical study using different pixelizations of the sphere demonstrates the effectiveness of our choice of approximation for spherical symmetry, where we report state-of-the-art on popular benchmarks for omnidirectional semantic segmentation and segmentation of extreme climate events.
