Image and Signal Analysis Group



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 using deep neural networks
  • Image reconstruction by deep generative networks
  • Analysis of ocular fundus optic disc, other lesions
  • Analysis of images of colonic pathology to describe tumor cell subpopulations in whole-slide images
  • Detection of prostate changes in multiparametric magnetic resonance imaging
  • Processing of full-frame histological images by machine learning methods.

Analysis of big data and development of deep learning algorithms:

  • Analysis and recognition of clonal structures in genetic data.
  • Analysis of traffic (marine) data to identify traffic anomalies in LSTM and transformer deep neural networks
  • Development of deep teaching / learning methods for solving classification and forecasting problems.
