The Third MUMIA training Summer school on "Information Retrieval and Interactive Information Access" is taking place at Heraklion, Crete, Greece on July 21-25, 2014. The aim of Training School is to give participants grounding in the core topics that constitute the interdisciplinary area of Multilingual and Multifaceted Interactive Information Access. The school is a week-long event consisting of lecturers from MUMIA and invited speakers. Among them, Stefanos Vrochidis of ITI-CERTH will be giving a lecture on "Interactive Content-based Multimedia Retrieval".The call for participation is available here.
The PERICLES project was proudly presented in one of the most important digital data related events in Europe and North America. The 9th International Digital Curation Conference, held this year in San Francisco, offered to its delegates a deep insight about the data-driven transformations in research, education, business and society. Our poster managed to win the best poster award out of many very interesting and fascinating projects.
The paper on “A Comparative Study on the Use of Multi-Label Classification Techniques for Concept-Based Video Indexing and Annotation” by Fotini Markatopoulou, Vasileios Mezaris and Ioannis Kompatsiaris received the Best Paper Award at the 20th International Conference on MultiMedia Modeling (MMM'14), which was held in Dublin, Ireland, in January 2014.
From the NEM community perspective, Big and Open data is becoming a hot topic as far as most of the content will be stored in the future in data centers and there is a need to optimize the usage of such infrastructure. This huge amount of data provided by the content sector (business content but also user generated content) will have to be stored, manipulated and retrieved from any one in the easiest way and on any type of devices. In addition, content will become more and more heterogeneous due to the multiplication of formats used by the end user devices. This increasing complexity needs further research activities that are highlighted in this position paper.
This document addresses several aspects of the Big and Open data domains and tries to provide a research agenda for the next years.
The poster entitled "Geometrically-Correct 3D OCT: A Novel Imaging Method for the Identification of High-Risk Coronary Plaque", which was co-authored by Multimedia Group and was presented in the G.D. Behrakis Cardiovascular Symposium in Vascular Biology 2013, received the best poster award. The Symposium was held at November 14, 2013, in Boston, MA, USA. The poster can be found here .

A new version of GPU-accelerated LIBSVM has been released. Version 1.2 supports the latest LIBSVM v3.17 & CUDA SDK 5.5. The binary and source files for both Windows and Linux are now available on Github, as well as under http://mklab.iti.gr/project/GPU-LIBSVM. Take a look at https://github.com/MKLab-ITI/CUDA/releases for a detailed change log.
Press Article for the Cooperation of ITI/CERTH with Hellenic Police/Forensic Sciences Subdivision of Northern Greece
A press article about the Cooperation of ITI/CERTH with Hellenic Police/Forensic Sciences Subdivision of Northern Greece is presented in the Έθνος newspaper (in Greek). The electronic version of the article is also accessible here.
The article describes the multimedia search technologies developed by ITI/CERTH with the guidance of Hellenic Police in order to automatically recognize pornographic material. This interactive multimedia search engine is evaluated by the Hellenic Police to facilitate the investigations on child pornography detection.
ITI/CERTH establishes cooperation with Hellenic Police/Forensic Sciences Subdivision of Northern Greece
The growth of electronic crime has called for the development of advanced analysis tools that could facilitate the tasks of digital forensic examiners. In this context, ITI/CERTH has established cooperation with Hellenic Police/Forensic Sciences Subdivision of Northern Greece, in order to integrate innovative multimedia technologies into dedicated forensic tools that could support the investigations of electronic crime.
During this cooperation, ITI/CERTH with the guidance of Hellenic Police has developed an interactive multimedia content-based search engine that is capable of retrieving multimedia content and automatically recognizing pornographic material. This search engine is evaluated and tested by the Hellenic Police, in order to be used for facilitating the investigations on child pornography detection.

Three papers from the Multimedia Group of the Information Technologies Institute will be presented in the 2013 IEEE International Conference on Image Processing (ICIP 2013), which will be held in Melbourne, Australia on September 15-18, 2013. ICIP, sponsored by the IEEE Signal Processing Society, is among the top international conferences in theoretical, experimental, and applied image and video processing. The papers are:
- Video Event Recounting Using Mixture Subclass Discriminant Analysis, by Nikolaos Gkalelis, Vasileios Mezaris, Ioannis Kompatsiaris and Tania Stathaki.
- Enhancing Video Concept Detection with the Use of Tomographs, by Panagiotis Sidiropoulos, Vasileios Mezaris and Ioannis Kompatsiaris.
- Discovery of Environmental Resources Based on Heatmap Recognition, by Anastasia Moumtzidou, Stefanos Vrochidis, Elisavet Chatzilari and Ioannis Kompatsiaris.
Sense the City is an application that allows citizens to get real time information regarding the environmental conditions in their city. This information is retrieved from several sensors that "sense" the city providing environmental measurements, such as temperature and concentration of pollutants (e.g. CO, CO2, NO2) that affect the air quality.
Sense the City is a web based application that has been developed within the European Project PEOPLE, in close cooperation with the Municipality of Thermi and user groups. It is therefore a truly user-centered digital application, adapted to the needs of Municipalities and local communities. The application is available in Greek and English, and provides air quality and temperature information for the area of Thermi in Thessaloniki. The Information Technologies Institute - Multimedia Group developed this application in cooperation with Draxis company as a subconstractor of the Municipality of Thermi.

The application is a Joomla component, which is open source and available here.
The Environmental Data Storage and Retrieval Service is a software, which supports storage, spatiotemporal indexing and retrieval of environmental information (e.g. air quality and weather forecasts, observations, historical data) as this is provided by nodes (e.g. sensors, stations, websites) that contain environmental measurements (e.g. weather conditions, air quality, pollen).
This implementation follows the Sensor Observation Service (SOS) 1.0 standard and builds upon 52°North SOS. This service has been implemented in the context of the European project PESCaDO, which deals with personalized orchestration and delivery of environmental information.
