Malvar wavelets on sphere
Xiang‐Gen Xia, Lei Zhang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1996
In this paper, Malvar wavelets defined on a unit sphere are introduced. They are constructed by using a similar technique of constructing 2D Malvar wavelets, where one dimension (theta) is periodic on (0, 2(pi) ) and the other dimension (phi) is not periodic on (0, (pi) ).
