Fast Principal Component Analysis for Cryo-EM Images
Nicholas F. Marshall, Oscar Mickelin, Yunpeng Shi +1
Principal component analysis (PCA) plays an important role in the analysis of cryo-EM images for various tasks such as classification, denoising, compression, and ab-initio modelin…
Autocorrelation analysis for cryo-EM with sparsity constraints: Improved sample complexity and projection-based algorithms
Tamir Bendory, Yuehaw Khoo, Joe Kileel +2
The number of noisy images required for molecular reconstruction in single-particle cryo-electron microscopy (cryo-EM) is governed by the autocorrelations of the observed, randomly…
Fast expansion into harmonics on the disk: a steerable basis with fast radial convolutions
Nicholas F. Marshall, Oscar Mickelin, Amit Singer
We present a fast and numerically accurate method for expanding digitized images representing functions on supported on the disk $\{x \in \mathbb{R}^2 : |x|…
On a linearization of quadratic Wasserstein distance
Philip Greengard, Jeremy G. Hoskins, Nicholas F. Marshall +1
This paper studies the problem of computing a linear approximation of quadratic Wasserstein distance . In particular, we compute an approximation of the negative homogeneous w…
