3D Visual-Spatial Perception
Learning-based Visual Localization
Our research centers on learning-based visual localization, which aims to infer precise camera 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 LiDAR scans. This enables robust localization by linking 2D observations with the 3D world geometry.
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
