REPOSITORY DESCRIPTION

This distribution is comprised of three repositories that use signal processing on the sphere and the group of rotations to compute affine-invariant shape descriptors, align models, and compute the reflective and rotational symmetries of a shape. The efficiency of the code is based on the fast signal processing code SpharmonicKit and SOFT which are included in the distribution.

NOTES

• The executable provided up was compiled for a 64-bit OS and requires the FFTW .dlls to run.
• Compilation requires the FFTW libraries.
• The SpharmonicKit and SOFT source code is slightly modified from the original to support faster computation on purely real input.
