FAST EXPANSION INTO HARMONICS ON THE DISK : A STEERABLE BASIS WITH FAST RADIAL CONVOLUTIONS
We present a fast and numerically accurate method for expanding digitized L × L images representing functions on [-1, 1]2 supported on the disk x ∈ R 2 : | x | < 1 in the harmonics (Dirichlet Laplacian eigenfunctions) on the disk. Our method, which we refer to as the Fast Disk Harmonics Trans...
