Open AccessSimcryocluster: a semantic similarity clustering method of cryo-EM images by adopting contrastive learning
Cryo-electron microscopy (Cryo-EM) plays an increasingly important role in the determination of the three-dimensional (3D) structure of macromolecules. In order to achieve 3D reconstruction results close to at...

Accurate structure from motion using consistent cluster merging
The incremental Structure-from-Motion approach is widely used for scene reconstruction as it is robust to outliers. However, the method suffers from two major limitations: error accumulation and heavy time con...

Accurate 3D motion tracking by combining image alignment and feature matching
We presents a novel method to improve the accuracy of 3D motion tacking. In contrast to the state-of-the-art tracking approaches, where the 3D structure of target is commonly approximated by a CAD model, the p...

Open AccessA single-model quality assessment method for poor quality protein structure
Quality assessment of protein tertiary structure prediction models, in which structures of the best quality are selected from decoys, is a major challenge in protein structure prediction, and is crucial to det...

Open AccessCryo-electron microscope image denoising based on the geodesic distance
To perform a three-dimensional (3-D) reconstruction of electron cryomicroscopy (cryo-EM) images of viruses, it is necessary to determine the similarity of image blocks of the two-dimensional (2-D) projections ...
