Title: Compression on the digital unit sphere

Authors: Mohamed Allali (Chapman Univ., Orange, CA, USA)
 
Abstract: 
 A method for compressing functions on the unit sphere is presented.
 This method is based on a Ramanujan set of rotations, and generates an
 equidistributed system of points. This method is flexible and easy to
 implement as it needs only few transformations to cover the whole unit
 sphere with spherical caps.
