Lixin Xue

I am a PhD student at ETH Zürich, supervised by Prof. Otmar Hilliges. My research interests mainly lie in computer vision and computer graphics, especially in the intersection of digital humans and neural fields.

Previously, I completed my master's degree at ETH Zürich. During my master, I did my thesis on neural faces in the Digital Humans Group at DisneyResearch|Studio, supervised by Dr. Paulo Gotardo and Dr. Derek Bradley. Prior to ETH, I did my bachelor's at Beihang University. I was lucky to work with Prof. Hao Su at UCSD and Dr. Zhirong Wu at Microsoft Research Asia.

Make COLMAP more robust to duplicated structures by filtering out wrong matches based on several state-of-the-art algorithms.

A fixed radius nearest neighbors search implemented on CUDA with a similar interface as pytorch3d.ops.knn_points with more than an order of magnitude speedup.

Design and implement an efficient library for arbitrary-precision ball arithmetic, achieving 60% of peak performance for the big integer multiplication.

Implement and compare different hybrid eulerian-lagrangian (PIC, FLIP, APIC) methods for fluid simulation.

Design a direction-based kernel for post-processing the network predictions to improve performance with limited data.

Achieve better localization accuracy on multiple datasets via a feature-metric loss optimized by LM algorithm.

Implement a ray tracer supporting global path tracing, volumetric rendering, and advanced denoising.
