Software Autofocus for UVC cameras under Linux. We have created a stand-alone autofocus application for Logitech USB cameras with proprietary motor focus extension. This application will allow you to automatically set the appropriate focus for a given scene in a few seconds. The underlying focus-from-image estimation has been integrated into guvcview, and beats all published approaches (according to our tests and to feedback from its...
Early-Warning System for Botnets. This project was initiated by Dr. Alexander K. Seewald and was conducted at the Research Lab Computational Technologies and Applications of the faculty for computer science of the University of Vienna under the leadership of Dr. Wilfried Gansterer. Previous research initiatives are focussed on the recognition and defense against unwanted or potentially harmful E-Mail messages (for simplification purposes named...
Online questionnaire system. We developed a system for creation, administration and evaluation of webbased questionnaires which is completely customizable. It can run on any server (system requirements: PHP 5, SQL database) or on our own server. All data is stored locally and is therefore completely under your control. It currently offers the following functions which can in each case be changed directly within the system. Questionnaires...
Automated Score Tuning for SpamAssassin. During the creation of an institute-wide spamfilter system based on SpamAssassin we have collected a set of 77,286 ham and spam mails from eight users, developed our own training methods and evaluated them against commercial and free spam filtering systems, including Symantec BrightMail 6. A more recent report puts the work in larger context, adds new empirical results and proposes a convenient approach...
Intelligent Go Board. In 2003, we built a prototype 8x8 board which records Go moves during normal play, thus ensuring that a full game record is available for each game. No special stones are necessary, no holes need to be drilled through the board - it is a nice example for Ubiquituous/Pervasive Computing. The technology used then was a capacitive matrix array, now made famous by its use in the iPhone and Android mobile phones - it's the...
Electronic Site Diary. The documentation of large building projects becomes ever more important. Only a complete documentation enables you to fight unauthorized demands or enforce your own justified demands - and avoid legal issues. The site diary plays an important role here. Our electronic site diary offers a standardised documentation which corresponds to the state-of-the-art as to what is necessary for site diaries. It is fast and easy to...
Augmented Reality (AR). We develop AR system which combine realtime camera video with virtual objects or otherwise modify it. We are especially concerned with markerless AR where no special markers are needed and where virtual objects can be anchored to arbitrary images or general faces.
Mobile Robot Toy Cat. In 1998/1999, we built a mobile robot toy cat based on the EyeBot-board and LEGO. While it was much fun and sometimes enlightening, ultimately we were sorely disappointed with the State-of-the-Art and now take only a cursory interest in this field. A short story to illustrate shortcomings of robotics technology: I had the pleasure to be one of the many spectators of RoboCup '99 in Stockholm which featured a Sony...
Analyzing C. elegans GFP images. Our long-term goal is to explain how the relatively small nervous system of C. elegans implements observable learning behaviour, in order to obtain inspiration for building new robust learning algorithms. First results as paper and code are already available, see below. This page describes the software accompanying the paper Quantifying Phenotypic Variation in Isogenic Caenorhabditis elegans...

OCZ Neural Impulse Actuator - Linux Driver. Together with Martin Bachem we developed a Linux driver for the OCZ NIA - a three-channel EEG with 1000 Hz sampling frequency. Internally, the hardware was licensed from Brain Actuated Technologies, makes this a very good system at a very low price. For example, the highly awarded system by g.tec Guger Technologies uses a similar hardware.Market price is currently about 100 EUR. We'd be happy to...
How to bluetooth-enabled your remote car. This is a step-by-step instruction on how to switch any common RC car to bluetooth control - i.e. creating a bluetooth-controlled car - like the one on the right, which was donated by my dear brother after years of collecting dust on his shelf. Although the steps seem quite simple and straight-forward to me, experience has dictated that the human capacity for miscomprehension is boundless - if in...
Poor Man's Gold Pocket Watch. This pocket watch simply shows the time. No bells, no whistles, no ticking.Based on the photograph of a one-handed pocket watch created by Breguet et fils, Paris, 1810, this small app shows the time.Available for AndroidTM from 2.1
