The industry that designs and promotes advertising products in television channels is constantly growing. For effective market analysis and contract validation, various commercial tracker systems are employed. However, these systems mostly rely on heuristics and, since commercial broadcasting varies significantly, are often inaccurate. This paper proposes a commercial tracker system based on the Block Operator Context Scanning (Block - OCS) algorithm, which is both accurate and fast. The proposed method, similar to coarse-to-fine strategies, skips a large portion of the image sequences by focusing only on Regions of Interest. In this paper, a video matching algorithm is also proposed, which compares image sequences using time sliding windows of frames. Experimental results showed 100% accuracy and 50% speed increase compared to traditional block-based processing methods. © 2012 Springer-Verlag.

A system performing sentiment analysis needs some prior knowledge which can be acquired, for example, by manual annotation only or by expanding a human-annotated sentiment lexicon by automatic means. However, users are seldom interested in all sentimental aspects at once, but rather look for opinion changes of some person (\Who) during some time period (\When) and depending upon \What, \Where or \Why something happened. The paper describes the work necessary to obtain and utilize such 5W annotations.

Fiber to the end-user (FTTx) has long been considered to be too expensive to be deployed to cover all end users especially those living in the far rural areas. The conclusion after working with some municipalities in Jamtland is now that FTTx is both technically and economically feasible. The architecture tested is an IP-Only broadband network capable of carrying end-user services up to 10/100Gbps to any point in the network. Building such a broadband infrastructure, is feasible mostly due to the fact that cost of standard IP-network components are diminishing and by utilizing novel network designs made possible because the limitations of the old Telecom infrastructure no longer apply and lastly that the take rate of permanent households is close to 100% due to the fact that the copper networks is removed. © 2012 IEEE.

The provision of publicly available Open Data targets to provide transparency in several public sector decisions and actions. However, this information is served massively and in different forms - mostly due to different bureaucratic procedures- while its diffusion does not occur at regular or at least generally predictable time intervals. Thus, even though the information is available by the involved public sectors and enterprises. citizens are overwhelmed from the size/inconsistency of the information they deal with. In this paper, we present a publicly accessible Web point (***/), which aims to promote transparency and enhance citizen awareness regarding public spending in Greece. The information is based on intelligent and semantic real-time processed open data that are derived from the open API of "Diavgeia" (Clarity) Program (***/en/) and TAXIS - Taxation information System (***/), while it is served through easily consumed visualization charts and diagrams. © 2012 Springer-Verlag.

We present a fast and precise vision-based software intended for multiple robot localization. The core component of the proposed localization system is an efficient method for black and white circular pattern detection. The method is robust to variable lighting conditions, achieves sub-pixel precision, and its computational complexity is independent of the processed image size. With off-the-shelf computational equipment and low-cost camera, its core algorithm is able to process hundreds of images per second while tracking hundreds of objects with millimeter precision. We propose a mathematical model of the method that allows to calculate its precision, area of coverage, and processing speed from the camera's intrinsic parameters and hardware's processing capacity. The correctness of the presented model and performance of the algorithm in real-world conditions are verified in several experiments. Apart from the method description, we also publish its source code; so, it can be used as an enabling technology for various mobile robotics problems.

Automatic decisional systems based on pattern classification methods are becoming very important to support medical diagnosis. In general, the overall objective is to classify between healthy subjects and patients affected by a certain disease. To reach this aim, significant efforts have been spent in finding reliable biomarkers which are able to robustly discriminate between the two populations (i.e., patients and controls). However, in real medical scenarios there are many factors, like the gender or the age, which make the source data very heterogeneous. This introduces a large intra-class variation by affecting the performance of the classification procedure. In this paper we exploit how to use the knowledge on heterogeneity factors to improve the classification accuracy. We propose a Clustered Localized Multiple Kernel Learning (CLMKL) algorithm by encoding in the classication model the information on the clusters of apriory known stratifications. Experiments are carried out for brain classification in Schizophrenia. We show that our algorithm performs clearly better than single kernel Support Vector Machines (SVMs), linear MKL algorithms and canonical Localized MKL algorithms when the gender information is considered as apriori knowledge. © 2012 Springer-Verlag.

Fuzzy ontologies extend classical ontologies to allow the representation of imprecise and vague knowledge. Although a relatively important amount of work has been carried out in the last years and they have been successfully used in several applications, several notions from fuzzy logic, such as fuzzy integrals, have not been considered yet in fuzzy ontologies. In this work, we show how to support fuzzy integrals in fuzzy ontologies. As a theoretical formalism, we provide the syntax and semantics of a fuzzy Description Logic with fuzzy integrals. We also provide a reasoning algorithm for a family of fuzzy integrals and show how to encode them into the language Fuzzy OWL 2. © 2011 IEEE.

The evolution of 60 GHz wireless networks using Orthogonal Frequency Division Multiplexing (OFDM) technique imposed requirements of increased processing in the baseband implementations. The current paper focuses on the design of a pipelined architecture realizing the baseband functions. The design bases on using parallel paths to achieve a throughput of 1.6 Gbps. The number of paths is configured at compile time to be 4, 8 or 16, for achieving maximal throughput by either using cutting edge technology FPGA platforms or target implementations with low cost devices. FPGA implementations validate the results. © 2011 IEEE.
