Orientation Estimation of Cryo-EM Images for Molecules with Arbitrary Symmetry by Semidefinite Programming
Yunpeng Shi, Amit Singer, Jinxin Wang +1
This paper extends the non-unique games framework introduced in Bandeira et al. (2020) to address symmetric structures. Precisely, we consider the problem \[ \begin{aligned} \under…

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…
