Our Members at Summer School of Biometry
2019-06-20, published by Jan Tinka

Martin Sakin and Jan Tinka spent a week at a biometry summer school organized by professor Massimo Tistarelli in Alghero in Sardinia, where they attended lectures and took part in discussions on topics ranging from person recognition based on iris to recognition based on gait patterns. The main topic of this year’s summer school was not only biometry but also application of deep learning methods and other machine learning for biometric purposes. Martin and Jan therefore returned from the school endowed with new knowledge, which will be helpful for their dissertation and research.

Our Student’s Work in a Radio and Newspaper
2019-05-22, published by Jan Tinka

The results of Jan Pawlus’ master’s thesis on imitation of handwriting characteristics were discussed in an interview aired on the Czech Radio (ČRo) and an article was printed by a Czech newspaper Právo. Jan Pawlus defended his master’s degree this year along with his thesis, which was supervised by Martin Drahanský. In his work Jan has designed and implemented a method of imitating static and dynamic characteristics of hand writing. To which he uses a special pen with sensors and a pen-equipped 3D printer. His method focuses on speed of writing and shows good results when replicating signatures. The newspaper article and radio broadcast discuss how his work is a contribution towards detection of signature spoofing. The text of the article can be found here  and a recording of the broadcast here  (both Czech only).

 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 Babí Lom Hill
2019-07-17

Since it had been quite a while since we last went to nature, we decided to take it easy with a comfortable climb of approximately 250 metres of elevation difference and jumping around the rocky Babí lom, which is close to a nearby town Lelekovice. Those of us who were feeling more adventurous took an even more action-packed, more rocky and less traveled path to Spálená skála rock. Even though the expected and allowed casualties were 1.5 group members, we didn't lose anybody (for too long), nobody got hurt and we even enjoyed the trip!

Disc Golf
2019-05-09

Everyone knows well the situation where every once in a while one wakes up in the morning and they and their friends just think of the exact same idea independent of each other. That didn’t happen to us. However, we were still able to agree that the time has come to entertain ourselves with something like golf, but less classy. Flatter. That’s why during one of the first warm sunny days we went out to play some disc golf. We were quite successful. Especially those who took the growing number of strokes as a good thing. Afterwards, we enjoyed an outdoor lunch in a restaurant.

Shooting
2019-03-05

While it is hard to believe, some of us not only hadn't owned any firearms but had also never held one in their hands. We needed to remedy that, which is why all the enthusiasts headed off to a shooting range to be embraced by the smell of gunpowder and some serious rumble, source of which could everyone choose to their liking.

Board Games
2019-03-04

One of the activities that most of us like to do are board games. That's why we decided to organize board games with friends in the cozy premises of the former student club. We ordered a meal that we could enjoy with a varied selection of drinks, even those of us who did not play any game at all. We played games only at the end of the event, the beginning and the middle was more oriented on discussion.

Laser Game
2019-02-25

After a long winter we decided there is nothing better than to get ourselves warm with a healthy exercise. That's why we again decided for running around frantically in a dark room while shooting lasers at each other with aggressive music and the flashing light of our vests enhancing the atmosphere. Not a single T-shirt stayed dry.

Christmas Party
2019-01-20

We gathered before Christmas so we could celebrate the end of the year together and say bye to each other before many of us travel home. We met at a pub in a cozy room with a fireplace, ate delicious food drank delicious drinks and, to help with the entertainment, we brought our favourite board games.

Again self defense
2018-03-09

Due to the previous success of the self-defense training, we went again to Židlochovice, where we learned from three experienced instructors the other bases of self defense. We learned how to defeat an attacker from various positions, including a knife attack. However, the most important finding is that it is the best to escape if the situation permits it. The second place is a crotch strike and then comes a series of self defense elements.

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.
