Perceptual and Cognitive Systems



 

The research in this area covers:

  • Biometrics: novelties in learning architectures and the improvement of the several facial recognition systems;
  • Improvement of the security of visual content: achieving good accuracy in printer-proof steganography with applications in the security of ID documents;
  • Analysis of endoscopic imagery for computer assisted surgery and diagnosis;
  • Analysis of images from capsule endoscopy for computer assisted diagnosis;
  • Analysis of images from deformable objects;
  • Solutions to incorporate causality and counterfactual inference principles in deep learning to enhance their interpretability, namely, Causal Representation Learning, Counterfactual Learning and Knowledge Distillation.
