CvgTalk-Lulu-Periocular Recognition

• Iris region is small, esp. from distance
• combine periocular region to increase detection region

Current status

• mostly use ideal faces and iris images
  
  • frontal face
  • high res. eye region image
• issues
  
  • only 2D

Proposed method

• 3D shape
• 2D LBP
  
  • to obtain 2D periocular region, first register 2D with 3D shape using facial landmark
  • 3D shape matching, ICP
  • distance matching score between probed periocular 3D point cloud and that from gallery
• fusion of 3D and 2D

Experiment

• Bosphorus DB
• 3D face dataset
• 105 subject
• 4,666 face scans

Results

• 3D > 20% better than 2D texture
• Intra-class variations
