Improving Resolution and Resolvability of Single Particle CryoEM using Gaussian Mixture Models

no code implementations31 Mar 2023 Muyuan Chen, Michael F. Schmid, Wah Chiu

Cryogenic electron microscopy is widely used in structural biology, but its resolution is often limited by the dynamics of the macromolecule.

DARCNN: Domain Adaptive Region-based Convolutional Neural Network for Unsupervised Instance Segmentation in Biomedical Images

1 code implementation CVPR 2021 Joy Hsu, Wah Chiu, Serena Yeung

In the biomedical domain, there is an abundance of dense, complex data where objects of interest may be challenging to detect or constrained by limits of human knowledge.

Capturing implicit hierarchical structure in 3D biomedical images with self-supervised hyperbolic representations

no code implementations NeurIPS 2021 Joy Hsu, Jeffrey Gu, Gong-Her Wu, Wah Chiu, Serena Yeung

To that end, we consider encoder-decoder architectures with a hyperbolic latent space, to explicitly capture hierarchical relationships present in subvolumes of the data.

Learning Hyperbolic Representations for Unsupervised 3D Segmentation

no code implementations28 Sep 2020 Joy Hsu, Jeffrey Gu, Gong Her Wu, Wah Chiu, Serena Yeung

There exists a need for unsupervised 3D segmentation on complex volumetric data, particularly when annotation ability is limited or discovery of new categories is desired.
