Education
Research Interests
- 3D object recovery in occluded environments.
- Range image segmentation using parametric models.
- Non parametric segmentation of 2D curves.
- Object Oriented Distributed Systems (see ABS European project).
- B-ISDN networks. (see W4ATT European project).
- Programming Languages.
Research Projects
- W4ATT(AC235). Diploma Thesis: Implemented the Server of the System, which aimed at providing all necessary information to a Java Applet, which displays the particular information graphically to the System's user. The target platform was primarily ATM experimental networks, but since the overall design of the Management Information Base of the System was generic, this can be easily extended to monitor TCP/IP networks as well. The whole system was implemented in the Java Language.
- ABS (AC206). Designed and implemented among other system components, a Query Plan Generator for the system based on an algorithm used in the Information Manifold project of Stanford University. This algorithm was enhanced and adjusted to the project requirements. More specifically the QPG is the heart of the ABS project which is dealing with generating a "guide" by the aid of which the system discovers where the information requested by the system's user resides.
- ABROSE (AC316). A knowledge acquisition system based on a cooperative intelligent agents network.
- 2DDepal. The cooperation of the University of Freiburg, institute of pattern recognition and image processing, with INOS GmbH , has resulted in the implementation of a framework which uses a KUKA industrial robot and a SICK LMS200 Laser Sensor, to detect boxes residing in a palette, grip them, and transfer them to a specific point away from the palette. This is a primitive system and incorporates a basis for a general depalletizing system, which will be able to perform the above described operations for a variety of target objects.
- Generic Depalletizing. Recently I was funded by the German government (Bundesministerium für Wirtschaft und Technologie) to develop a robotic system which will be able to localize box-like objects and sacks jumbled on source platforms, grasp them and pile them to target platforms.
Teaching Experience
- Teaching Assistant in the Microcomputers laboratory course of NTUA (Spring 1998)
- Electronics and Digital systems for foundation college (Fall 1998)
- Assisted undergraduate course “Algorithms for Digital Image processing”. (Spring semester 2001,2002,2003)
Professional Experience
- National center for Scientific Research, "Demokritos". May 1998 - December 1998. Worked as a developer on the GEONICKEL project. More specifically I was involved in the development of the GEOES expert system. The GEOES system embodies the knowledge of geo-experts and aims to facilitate the exploration process performed by geo-scientists. It is an expert system with a user-friendly interface that runs under the Windows 95 and the Windows NT operating systems. GEOES is integrated within GEOSIS, the software toolbox of the GEONICKEL project. The system gives emphasis on the integration of a variety of different approaches for the Ni exploration tasks, combining a wide range of data and knowledge from all the geo-domains involved.
Tools used: TCL/TK 8.0, Sicstus Prolog 3.0.
- INOS Hellas. January 1999 - September 1999. Worked in the R&D towards the development of a generic framework which elicits control on sensing industrial robots. Implemented:
- The Display Driver functionality (System visualization group)
- The Intersection Calculation functionality (This is widely known at the literature as 3D object reconstruction. Intersection Calculation gives the robot the ability of stereo vision.)
Tools used: C++ STL, MFC (MSVisual C++ 6.0).
