Fast rigid rotational alignment of voxelized 3-D density maps in sliced Wasserstein distance
Oscar Mickelin, Yunpeng Shi, Amit Singer +1
We develop a fast method for the rigid alignment of voxelized three-dimensional density functions over using sliced optimal transport. Our approach efficiently tra…
Fast rigid alignment of heterogeneous images in sliced Wasserstein distance
Yunpeng Shi, Amit Singer, Eric J. Verbeke
Many applications of computer vision rely on the alignment of similar but non-identical images. We present a fast algorithm for aligning heterogeneous images based on optimal trans…
Algebraic Constraints and Algorithms for Common Lines in Cryo-EM
Tommi Muller, Adriana L. Duncan, Eric J. Verbeke +1
We revisit the topic of common lines between projection images in single particle cryo-electron microscopy (cryo-EM). We derive a novel low-rank constraint on a certain $2n \times…
Moment-based metrics for molecules computable from cryo-EM images
Andy Zhang, Oscar Mickelin, Joe Kileel +4
Single particle cryogenic electron microscopy (cryo-EM) is an imaging technique capable of recovering the high-resolution 3-D structure of biological macromolecules from many noisy…
