This paper presents an approach to unsupervised, content based classification and lookup of multi-dimensional objects such as pictures, audio and video, which could be used to accelerate online searches of such data sets and real-time biometrical recognition and classification which uses them. The approach treats the classification and lookup as a generic pattern matching problem. On contrary to the traditional correlation oriented method, this approach adopts Principle Component Analysis (PCA) to create a representation which will be used as an index to a particular data set. This results in a fewer dimension identity of the object, that can be looked up in shorter time, provided the approach always consider the first n components for matching. Further the outcome of PCA will be classified through dendrogram clusterization that will result in a system similar to a hash table. The framework provides hash function like system to speedup lookups and recognitions. The article introduces to the problem of classification of non-textual data and inherent limitations. It further describes the advantage of using PCA as an alternative to pattern matching and leads through the methodology in developing dendrogram clusterization based online management and lookup.

VideOlympics 2009
VideOlympics Showcase
Demo sessions of video retrieval systems are ideal venues to disseminate scientific results. Existing demo sessions, however, fail to engage the audience fully. Real-time evaluation of several video retrieval systems in a single showcase increases impact. Encouraged by the success of previous editions, we will again organize a VideOlympics showcase at the ACM International Conference on Image and Video Retrieval.
The major aim of the VideOlympics is to promote video retrieval research. An additional main goal of the VideOlympics is giving the audience a good perspective on the possibilities and limitations of the current state-of-the-art systems. Where traditional evaluation campaigns like TRECVID focus primarily on the effectiveness of collected retrieval results, the VideOlympics also allows to take into account the influence of interaction mechanisms and the advanced visualizations in the interface. Specifically, we aim for a showcase that goes beyond the regular demo session: it should be fun to do for the participants and fun to watch for the conference audience. For all these reasons, the VideOlympics should only have winners. Similar to previous years, a number of TRECVID participants will simultaneously do an interactive search task during the VideOlympics showcase event.
New in 2009
For the first time, we will include in the 2009 edition of the VideOlympics a round with novice users, in addition to the round with expert users. The novice users will be selected from a group of high-school teenagers from the island of Santorini, for whom it can be assumed that they have a decent English language level. Moreover it is allowed to provide each novice user with a short training session with your video search engine (amount to be defined).

ImageCLEF 2009
ImageCLEF is the cross-language image retrieval track run as part of the Cross Language Evaluation Forum (CLEF) campaign. This track evaluates retrieval of images described by text captions based on queries in a different language; both text and image matching techniques are potentially exploitable.
The details of all the databases for ImageCLEF 2009 will still need to be defined. Registration will open in early February and registration forms will be available from the CLEF web pages.
The following tasks are planned in 2009:
* a photographic retrieval task,
* a medical retrieval task,
* a robotic image visual task,
* a medical automatic image annotation task, and
* an image retrieval task from a collection of wikipedia images.
More information on the details of these tasks will follow shortly.
Schedule
The exact schedule will depend on the individual tasks and is still subject to changes as we have not yet received the copyright for all databases we would like to use.
A tentative global schedule can be found here (please look at the page of each task for more details):
* 15.1.2009 : registration opens for all CLEF tasks
* 15.3.2009 : data release
* 15.4.2009 : topic release
* 15.5.2009 : submission of runs
* 15.7.2009 : release of results
* 15.8.2009 : submission of working notes papers
* 30.9-2.10.2009 : CLEF workshop in Corfu, Greece

Lego NXT Vision - Robot View
Adding a simple wireless camera to your Lego NXT Mindstorms can turn your robot into a machine vision solution. We added a camera to our TriBot and now it can find balls and cones. In this video you will see the robot performing its task of picking up a blue ball and moving it towards an orange cone. You can find out how we did all of this using the RoboRealm robot vision software at http://www.roborealm.com/ Just check out the tutorials section. Read more
