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
