Welcome to the PRML Lab!

The PRML Lab at Gachon University is led by Prof. Sang-Woong Lee. We mainly focus on developing computer vision algorithms for tasks like face recognition, action recognition, cancer detection, parking-lot occupancy detection, intelligent solar panel fault detection, etc. We are mainly interested in the following research areas:

  • Face Recognition
  • Action Recognition
  • Medical Image Analysis
  • Object Classification
  • Image Segmentation
  • Object Detection
  • Bioinformatics
