CVPR 2025

Proposed GCC (Generative Color Constancy), a novel approach that leverages pretrained diffusion models (Stable Diffusion) to estimate scene illumination by generating color checkers into images, enabling auto white balance across different camera sensors without requiring camera-specific training.

CVPR 2025

SpectroMotion 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.

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.

VAE based Sentiment Analysis

Employing a Variational Autoencoder (VAE) model to perform sentiment analysis by mapping sentence embeddings, derived from a pre-trained BERT model, into a latent space composed of Arousal and Valence dimensions.

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.

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.
