  • Abstract
    A fast algorithm for the computation of spherical harmonic expansions of bandlimited functions on the 2-sphere is described. The algorithm also provides for an efficient inverse transform (synthesis) as well and consequently fast convolution on the 2-sphere is also possible. We discuss applications to image processing and medical imaging as well as aspects of our working implementation
