Center node: "a novel sampling theorem on the rotation group"
  Abstract: We develop a novel sampling theorem for functions defined on the three-dimensional rotation group   ${\rm SO}(3)$   by connecting the rotation group to the three-torus through a periodic extension. Our sampling theorem requires   $4{L^3}$    samples to capture all of the information content of a signal band-limited at   $L$   , reducing the number of required samples by a factor of two compared to other equiangular sampling theorems. We present fast algorithms to compute the associated Fourier transform on the rotation group, the so-called Wigner transform, which scale as   ${\cal O}({L^4})$   , compared to the naive scaling of   ${\cal O}({L^6})$   . For the common case of a low directional band-limit   $N$  , complexity is reduced to   ${\cal O}(N{L^3})$  . Our fast algorithms will be of direct use in speeding up the computation of directional wavelet transforms on the sphere. We make our   ${\tt SO3}$   code implementing these algorithms publicly available.
