I am a Ph.D. student in computer science highly interested in physically based rendering. Specifically, my research aims to accelerate physically based rendering methods via deep learning. Not limited to this, I m also interested in recent rendering techniques such as implicit neural representations and differentiable rendering, which I did some projects about these areas. I’m looking forward to the day when people can enjoy realistic rendering anytime and anywhere!
Research Interest
Ray Tracing, Physically Based Rendering, Neural Rendering, Computer Vision, Deep Learning

Contribution of Auxiliary Features to Monte Carlo Denoisers Based on Deep Learning (2021)
Research Project (Excellence Award on Undergraduate Research Program in 2021)
◦
Analyzing & Enhancing contributions of auxiliary features (albedo, normal, and depth) by adding channel attention to existing denoisers
◦
Applied multi-task learning by adding auxiliary tasks of reconstructing auxiliary features from a denoised image to enhance the semantics of auxiliary features
•
Scene Generator with Blender 2.93 (2021)
Research Project
◦
Generates scenes with various camera, material, and lighting settings by path-tracing using Cycles renderer supported by Blender
◦
Extracts geometric features (albedo, normal, depth) of each scene
◦
Current Monte-Carlo denoising methods involves deep learning which requires a lot of data. This scene generator is expected to make rich training dataset for this task easily.
