Computer vision is a science discipline with an ultimate goal to perceive, to interpret and to understand the natural images or other type of visual data.
The research in the field of computer vision is focused mainly on:

  • Medical image processing : CT and MRI radiological data processing, detection of anatomical anomalies, segmentation and 3D image registration.
  • Prediction of visual human attention: development of model of human visual attention, generation of visual saliency map.
  • Visual object detection and object recognition: development of novel methods of object detection and object recognition using 2D and 3D visual data.

In the area of information visualisation are the key research topics:
novel interaction techniques in visualization, data visualization in virtual reality and augmented reality.
Research task in computer graphics are mainly photorealistic visualization, real-time rendering, light-field capture and manipulation.

Keywords:
Medical Imaging, Object Detection and Object Recognition in 2D / 3D, Visual Attention Prediction, Augmented and Virtual Reality Applications, Big Data Visualization
