  1. Center for Machine Perception • Belongs to: • Czech Technical University in Prague • Faculty of Electrical Engineering • Department of Cybernetics (head Prof. Vladimír Mařík) • Head:Prof. Václav Hlaváč • http://cmp.felk.cvut.cz

  2. Group outline and interests • University research group established as a computer vision lab in 1986. • Computer vision, pattern recognition, mathematics of uncertainty • 26 staff members (2 profs., 2 assoc. profs., 6 assist. profs., 13 researchers, 3 support staff) • 10 full time PhD students, 15 MSc student theses in progress. Omni Stereo Reconstruction Recognition Tracking Medical

  15. Deformable surface matching asMarkov Random Field optimization • Given two images, estimate a mapping from one image to another providingbest visual alignment. • We apply discrete approximation over large search space. Video, click on it.

  16. Multicamera tracking Video, click on it.

  17. Medical Imaging • Image registration • Parallel MRI reconstruction • Object detection in ultrasound signal • MEG/EEG reconstruction elastic registration of cervical uterus images } deformation map

  18. Medical Imaging

  19. Airborne surveillance • Cooperation with Czech Airforce R&D unit • Unmanned aerial vehicle • The aim is the detection of moving vehicles on a ground (speed 20-150 km/h) • Compensation for own UAV motion necessary

  20. UAV, tracked vehicles Video, click on it. Red and blue blobs point to moving vehicles. Two colors allow to distinguish the movement direction.

  21. Tracking, stabilization Video, click on it.

  22. Tracking, stabilization 2 Video, click on it.

  23. Stabilized camera head • Developed on the Czech Air Force demand of from 2006 to 2008. • Two CTU teams: Dept. of Cybernetics and Dept. of Control Engineering. • Two feedbacks: • the fast one dumps vibrations of the UAV, • the slow one tracks the target.

  24. Stabilized camera head, test Video, click on it.

  25. Sputnik tracker • Tracking with a companion. • Finds the companion automatically. • Does not loose tracks when the template is not visible. Video, click on it.
