Abstract [en]

Many kinds of data have a spherical representation, the idea is to tessellate the "sphere" in an efficient way and then decode the data so it can be compressed easily. In this paper, the process of exploration will start from the basic spherical wavelet-like to some new tessellation compression techniques in 3D to decompose the sphere with squares or triangles. The produced tessellation will have more round corners and the artefacts will be less prominent. Earth map will be textured on the sphere to compare the effect of different compression techniques.
