Fast Convolutions on $Z^{2} \ S E (2)$ via Radial Translational Dependence and Classical FFT

Arash Ghaani Farashahi, Gregory S. Chirikjian

Let $Z^{2} \ S E (2)$ denote the right coset space of the subgroup consisting of translational isometries of the orthogonal lattice $Z^{2}$ in the non-Abelian g…

Asymptotically Steerable Finite Fourier-Bessel Transforms and Closure under Convolution

Arash Ghaani Farashahi, Gregory S. Chirikjian

This paper develops a constructive numerical scheme for Fourier-Bessel approximations on disks compatible with convolutions supported on disks. We address accurate finite Fourier-B…

Deblurring of Motionally Averaged Images with Applications to Single-Particle Cryo-Electron Microscopy

Wooram Park, Daniel N. Rockmore, Dean Madden +1

This paper addresses the deconvolution of an image that has been obtained by superimposing many copies of an underlying unknown image of interest. The superposition is assumed to n…
