Research fields

 Speech and language processing:

  • Speech signal modelling: autoregressive/linear prediction, fractal-based nonlinear modelling, source-filter models.
  • Speech recognition: segment-based speech recognition.
  • Speech emotion recognition: hierarchical classification of speech emotions, speech emotion features, feature selection.
  • Estimation of speech quality: acoustic analysis for quality estimation; estimation of vocal fold functionality; estimation of phonation level;
  • Signal model parameter assessment;
  • Development of sound mathematical models.

 Image and video signal processing:

  • Object recognition and segmentation.
  • Movement detection.
  • Optical flow analysis.
  • Image restoration.
  • Machine and deep learning methods development for image analysis.
  • Medical image analysis: ophthalmic, microscopy, cell classification, MRI data processing.

 Deep learning and big data analysis:

  • Abnormal marine traffic detection.
  • Tumour heterogeneity evaluation.
