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).
In the issue 23/2017 of the journal TÉMA there is an interview with Cpt. Ing. Martin Spurný and assoc. prof. Martin Drahanský about camer systems. The interview is oriented on use of camera systems and their impact to our privacy. In regard of the fact that Cpt. Spurný is a forensic expert with specialization on digital image and video analysis by Czech police, there is a discussion in the article about impact of camera systems to criminal investigation. The whole text could be found here (available only in Czech).
Martin Drahanský actively visited the trade fair and conference LEA-DER held in Prague on 25.-26. April 2017. Together with research outcomes of the STRaDe research group at the stand he presented two topics – processing of fingerprints with damages and diseases and detection of weapons in video. The data was prepared by Ondřej Kanich and Michal Dvořák. The visit was successful and we hope to get new opportunities for our results.
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 .
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.
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 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 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.
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.
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.
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).
Research and creation of fingerprint spoofs for testing liveness detectors and used fingerprint sensors.
New methods of specific damage of synthetic fingerprints and their usage.
Within our research activities we cooperate with many academic partners. In the following list there are some of them:
