Research group STRaDe is a part of Department of Intelligent Systems at Faculty of Information Technology of Brno University of Technology. Main focus of the STRaDe group is research and development in the field of security technologies with accent on both hardware and software aspects. Security technologies involve wide spectra of applications and devices. Huge area, which we are interested in, is biometrics whereas we focus nearly on all up to date technologies and metrics - for example acquisition and recognition of fingerprints, eye irises and eye retinas, 3D faces and 3D hands, vein patterns, liveness detection of various biometric characteristics, etc.
The second and no less important part of our research is area of sensoric systems and its application in robotics which is our particular research aim itself. In connection with robotics and biometrics research in area of complex intelligent systems is done. Next part of our research activities is video processing and its implementation in hardware (including acceleration in hardware), where it takes a place as computer vision for various systems and applications.

A great test of light sources
2017-07-14, published by Martin Drahanský

A press release  (available only in Czech) for extensive testing of light sources together with colleagues from University of Applied Sciences in Vorarlberg and FCE BUT was published on the BUT web page. In this testing, the properties of 53 light sources from 18 manufacturers were tested. The measured values of the most light sources correspond to the data on the packaging. For some, however, values varied (e.g. power consumption) or, eventually we were surprised (the start-up time to full operation of the source took almost 10 minutes). Czech Television also made a short report   (available only in Czech) about the achieved results and derived conclusions. The Brno daily Rovnost published a report that can be viewed here  (available only in Czech).

On 03. March 2017 there was made and shown a short document in TV news at Czech Television (ČT) about our research in processing and generation of fingerprints with damages. There were especially presented differences between undamaged and damaged fingerprints, furthermore there were discussed differences between damages caused by environment and diseases. At the same time there was presented our application for generation of damages into synthetic fingerprints. The short document could be seen HERE .

 AREAS OF INTEREST

Biometrics

Biometrics

Biometrics includes many interesting topics. We focus mainly, but not only, at fingerprints. Other topics we deal with belong the iris and retina recognition and recognition based on 3D scans of face or hand. A big part of our research is focused at liveness detection and sensor quality analysis.

Biomedicine

Biomedicine

Biomedical applications are very closely related to the biometric systems. The biggest emphasis in STRaDe is put on detection and recognition of skin diseases on fingers and retina diseases. These areas are important for us, since they are part of biometric technologies we are dealing currently with.

Robotics

Robotics

Robotics has not been our main focus. However, we needed a platform to present and proove functionality of our computer vision algorithms and we applied for a robotic grant then, hence we accepted very challenging task to create our own platform, which would be useful for rescue teams of all sorts. Result of this is our robotic unit RUDA.

Computer Vision

Computer Vision

Computer vision is very tightly related to biometric systems, since you need to acquire an image from a camera system to get biometric features in most cases. Even the basic principles of data processing are very similar to algorithms and techniques of the computer vision.

 CURRENT RESEARCH

Liveness Detection

Our research of the liveness detection aims at biometric technologies based on the fingerprints, finger or hand veins, face and eye. In this field we registered a few patents and utility models.

Recognition of eye diseases

Research of the eye diseases recognition is aimed at recognition of symptoms of various eye diseases in an image of iris and retina, where are the symptoms to be recognised best.

Influence of the skin disease on the fingerprint recognition

In 2008 we started dealing with issues of influence of various finger skin diseases on the fingerprint recognition process. To improve our knowledge and to base it on reliable information, especially from the medical point of view, we made fingerprint skin diseases our common cause with the dermatologists from St. Anne's University Hospital Brno, University Hospital Olomouc and a private dermatological clinic in Darmstadt (Germany).

Fingerprint Spoofs

Research and creation of fingerprint spoofs for testing liveness detectors and used fingerprint sensors.

Synthetic Fingerprints

New methods of specific damage of synthetic fingerprints and their usage.

 TEAM EVENTS

Hike to Soběšice to the watchtower “Ostrá horka”
2017-06-10

On Friday in the morning we went to a short hike to the watchtower in Sobešice. We used the way through shaggy footpaths, along the Rabbit creek (Zaječí potok) till the watchtower "Ostrá horka". On the way we found one geocash. The trip was successful - we returned back without any tick on our bodies.

Ninepins
2017-06-10

What about to play the game ninepins? We have an experience with bowling, but with ninepins... Therefore we went to the friendly restaurant "U Kosa" in Brno-Komín, where we indulge in playing this game. The ball does not have any hole and is smaller, indeed we achieved the same shining results as in bowling. To hit all the pins was not possible... We cannot earn our own's living with this activity...

Laser game
2017-03-16

We decided to run in a dark and foggy room and shoot to each other using laser beams. And how successful we were. Some of us looked like a zombie , however we exchanged a lot of hits. Let's say three times "hi" to the laser with wavelength 650 nm!

Escape game 2
2017-02-28

In a little bit different crew, again with a foreign guest, we attended another escape game - Logiq Game . We escaped 5 minutes before the time limit. We are pretty good...

Escape Game 1
2017-02-09

One gloomy January day we decided to be locked. And therefore we did it. We were split up into two groups - the main criteria was gender and race balance, language skills and unfamiliarity with the expected adventure. We went to the jails and solved two escape game stories Cuckoo's Nest and Heritage of Cyril Wanieck in BrainFAQ .

Hike over Palava hills
2016-09-15

We decided to hike over Palava hills. We walked approx. 20 km and looked forward to wine in Mikulov, however vainly - many restaurants were already closed and wine cellars not opened yet...

Self defence course
2016-08-16

Another self destructive activity, which we happily applied on our bodies, was a self defence. I think that after the initial sweating out of all water from our bodies, everything was stable and we enjoyed this event.

Grilling and board games evening
2016-06-27

Probably the last meeting in this academic year was carriend on a wave of perfect amusement at a gril and board games Kemet  and Osadníci z Katanu  by a massive participation in the last time.
