Real-time object detection 
and  tracking

The aim of this research is to develop a real-time object detection and monitoring system for industrial factory environments that can recognize human workers and detect potential hazardous situations using DNNs combined with image processing techniques. We have a robust tracking technology that can cope with coverage blind spots.

Intelligent data extraction from drawings and documents

The aim of this research is to extract information from documents or engineering drawings, and convert into an excel form that can be used for digital trasnformation. We implement the automated data extraction  system using VLM, LLM, fine-tuning, DNN, and image processing.

Physical AI research: minimizing 
sim-to-real gap

Our lab is building a Physical AI research platform on NVIDIA Isaac Sim and Isaac Lab to train and validate embodied intelligence for real-world robotic systems. We integrate VLA models with object detection and segmentation pipelines, enabling robots to perceive, reason about, and act within complex physical environments.

Display to camera communication

Display to camera (D2C) communication is a promising candidate for short-range M2M communication with a display–camera link. The D2C system must deliver seamless and ubiquitous communication and must enable successful acquisition of the embedded data on the receiver side. We apply this technology to data security applications such as steganography and digital watermarking.

Medical data analysis and processing

We provide AI-powered medical image analysis services that assist clinicians in diagnosis. Our technology automatically analyzes 3D medical images through segmentation and object detection to identify organs and lesions, and accurately measure their size and volume. Based on the analysis results, our system can automatically generate standardized clinical reports using 
SNOMED CT terminology.

Satellite and HAP image-based 
remote sensing

This research aims to develop a real-time object detection and tracking system using satellite and HAP-based remote sensing imagery. By leveraging DNN-based detection models and image processing techniques, the proposed approach enables continuous wide-area monitoring and identification of potential risks in large-scale environments.

Time series data analysis

An objective of time series analysis is to explore and understand data patterns in changes over time. We possess expertise in applying machine learning techniques, LSTMs and Transformers, to identify patterns and extract meaningful insights from complex time-series  data. We specialize in real-time analysis of physiological signals collected 
from wearable devices.

IoT with open source hardware

The edge AI ecosystem has benefited greatly from the open source availability of libraries and open hardware. We implement extensive AI-assisted systems with open source hardwares including Jetson Orin, Xavier, etc.
