Perception and modelling of dynamic environments

LIVIA's techniques solve concrete and complex problems, including detecting tumors or patient depression levels where massive datasets have limited annotations.

// Fields of application
  • Analysis of medical, satellite, aerial and other images
  • Biometrics: recognition from signature, face, voice, etc.
  • Automatic processing of handwritten documents
  • Affective computing for health monitoring
  • Safety and surveillance
