The topics I am interested in are:

• signal coding and compression
  • vocoders principles: LPC based
  • pitch-based vocoder
  • text2speech and speech2text like an alternative to the GSM codecs
  • methods for accurate and fast pitch extraction
  • texture modeling by using methods from speech
    

• biometrics
  • face detection and tracking
  • face authentication and recognition
  • speech authentication and recognition
    
    
    
• cellular neural networks
  • fast pre-processing for authentication/recognition by means of CNNs
    
    
• software and hardware parallel architectures
  • arithmetic unit working with complex numbers
  • solutions for systolic and parallel implementation of orthogonal transforms
