Moment Constraints and Phase Recovery for Multireference Alignment
Vahid Shahverdi, Emanuel Ström, Joakim Andén
Multireference alignment (MRA) refers to the problem of recovering a signal from noisy samples subject to random circular shifts. Expectation--maximization (EM) and variational app…
cuFINUFFT: a load-balanced GPU library for general-purpose nonuniform FFTs
Yu-hsuan Shih, Garrett Wright, Joakim Andén +2
Nonuniform fast Fourier transforms dominate the computational cost in many applications including image reconstruction and signal processing. We thus present a general-purpose GPU-…
Time-Frequency Scattering Accurately Models Auditory Similarities Between Instrumental Playing Techniques
Vincent Lostanlen, Christian El-Hajj, Mathias Rossignol +3
Instrumental playing techniques such as vibratos, glissandos, and trills often denote musical expressivity, both in classical and folk contexts. However, most existing approaches t…
Factorization of the translation kernel for fast rigid image alignment
Aaditya Rangan, Marina Spivak, Joakim Andén +1
An important component of many image alignment methods is the calculation of inner products (correlations) between an image of pixels and another image translated by so…
