I am currently a Master’s student in Institute of AI Innovation at National Yang Ming Chiao Tung University, advised by Prof. Yu-Lun Liu and Prof. Jiun-Long Huang. I received my Bachelor's degree in Electronic Engineering from National Taipei University of Technology. My research interest focuses on 3D scene reconstruction and diffusion models in low-level vision tasks. I have a cute girlfriend and her name is Alice Tung 🫡. Here is her instagram link!

CVPR 2025 🔥

Proposed GCC (Generative Color Constancy), a novel approach that leverages diffusion models to estimate scene illumination by inpainting color checkers into images, enabling color constancy across different camera sensors without requiring camera-specific training.

SpectroMotion: Dynamic 3D Reconstruction of Specular Scenes

Cheng-De Fan, Chen-Wei Chang, Yi-Ruei Liu , Jie-Ying Lee, Jiun-Long Huang, Yu-Chee Tseng, Yu-Lun Liu

CVPR 2025 🔥

SpectroMotion is presented, a novel approach that combines 3D Gaussian Splatting with physically-based rendering (PBR) and deformation fields to reconstruct dynamic specular scenes and is the only existing 3DGS method capable of synthesizing photorealistic real-world dynamic specular scenes.

Project

DS3DGS: Dynamic Specular 3D Gaussian Splatting

Our proposed approach, DS3DGS, expands 3DGS by adding a deformation field with specular surface rendering, significantly improving the quality of dynamic specular scene reconstruction.

RESTful Web Game Platform

Developed an interactive web gaming platform featuring user authentication, two classic games (Whac-A-Mole and Snake), and a real-time leaderboard system implemented with RESTful APIs. Utilized HTML, CSS, JavaScript, Express.js, and SQLite to create a responsive front-end interface with a back-end database that stores user profiles and game scores for competitive ranking.

Golf Ball Trajectory Estimation System,

This project focuses on developing a golf trajectory estimation system that uses high-speed cameras and image processing algorithms to calculate and simulate golf ball trajectories. The system captures key parameters such as initial velocity, launch angle, and deviation angle, and displays the trajectory through a web interface.
