Projects
Funded research projects of the team — from autonomous underwater vehicles for aquaculture to biometrics, document analysis and open education platforms.
AUV Creation for Fisheries — Fish Quality Control
The project concerns the construction of a robotic underwater vehicle (ROV) for the inspection and repair of fish farms in Greece using Computer Vision, in order to identify anomalies and damage. The vehicle also collects measurements for research and improvement of the growth rate of the products, while, on a second level, fish quality control and evaluation of nutritional value is carried out through specialized indicators (eicosapentaenoic and docosahexaenoic acid, biogenic amines, trimethylamine and others).
The intent of this work is the use of robotics and computer vision to make net inspection easier, safer and cheaper for aquaculture units — a demanding need for the Greek aquaculture industry, especially in remote coastal and island areas. The technology was patented (Greek Industrial Property Organisation — OBI).

Creation of a Multimodal Biometric Password using Steganography
Recent device implementations require biometric features to unlock devices to ensure greater security; such systems mainly use computer vision algorithms to analyze images and identify users. However, research has shown that biometric identification can be cheated using fake biometric features.
To address this and simplify user identification, the project proposes a multimodal biometric code, generated by combining the user’s biometric features with a sealing (steganographic) process, making it unique to each individual. Various feature combinations were explored and their security experimentally demonstrated.

Document Image Layout Analysis
Development of a Windows desktop application for advanced document processing, consisting of a Graphical User Interface (GUI) and a specialized Dynamic Link Library (DLL). The technical workflow: ingestion of high-quality document images (newspapers, journals, magazines); DLL-driven segmentation of pages into non-overlapping blocks; classification of blocks into Text or Graphics (logos, photos, diagrams); and output of XML files containing bounding polygon coordinates and block classes.
Development utilized real-world image samples provided by the client for system training and performance evaluation.
