Our Research Areas
3D Visual-Spatial Perception
Learning-based 3D Localization
Our research centers on learning-based 3D localization, which aims to infer precise 3D poses using deep learning techniques. Among various approaches, we explore Scene Coordinate Regression (SCR)—a method that predicts dense or sparse 3D scene points directly from sensor data like 2D images or 3D scans. Not only limited to single modality approaches, we explore sensor-fusion based localization methods to remain robust against outdoor environment.
Privacy-Preserving Visual Localization
Developing techniques that enable visual localization while protecting privacy concerns through methods like paired-point lifting and 3D ray clouds.
3D Object Reassembly and Reconstruction
Reconstructing the original shape of heritage ceramics from multiple fragments using advanced 3D modeling and matching techniques.
Multimodal AI for Industrial Anomaly Detection
Generative AI for Anomaly Image Generation
Development of a Few Shot-based AI Algorithm for Augmentation and Generation of Defect Data.
Vision-Based Defect Detection
Developing algorithms for detecting industrial defects and generating synthetic defect images for training robust models.
Video Anomaly Detection
Detecting anomalous human behaviors in video surveillance through unsupervised and semi-supervised learning approaches.
Medical-Spatial AI
Physics-Informed AI
Using axes-aligned spatiotemporal Gaussians and a physics-informed normalized splatting scheme to efficiently super-resolve 4D flow MRI data.
Medical Image Segmentation and 3D Reconstruction
CT-based carotid artery segmentation and 3D vessel structure reconstruction for improved medical diagnosis and treatment planning.
Hand Gesture Recognition
Developing hand gesture recognition systems with HoloLens 2-based mixed reality technology for intuitive human-computer interaction.
