Curvilinear structures are useful features in a variety of applications. Compared to other commonly used features such as edges, there is relatively few work on curvilinear structure detection and its performance evaluation. In this paper we propose a novel supervised methodology for evaluating the performance of curvilinear structure detection algorithms. We consider the two aspects of perform...

In large telecommunication networks, alarms are usually useful for identifying faults and, therefore solving them. However, for large systems the number of alarms produced is so large that the current management systems are overloaded. One way of overcoming this problem is to analyse and interpret these alarms before faults can be located. Two different techniques were developed and setup to re...

We present a fully implemented expert diagnostic system which evaluates the performance of SMEs on a benchmarking basis. The system has been in use for several years and has gone through a constant and quite challenging evolution in order to meet both the needs of research and the production of benchmarking reports. We discuss why we decided to upgrade our system with data warehousing and data ...

We propose a novel appearance-based method for person re-identification, that condenses a set of frames of an individual into a highly informative signature, called the Histogram Plus Epitome, HPE. It incorporates complementary global and local statistical descriptions of the human appearance, focusing on the overall chromatic content via histogram representation, and on the presence of recurre...

The paper presents a modelling approach for performance comparison of Central European companies on three levels: country, industry, and company. The approach is based on Data Envelopment Analysis and Analytic Hierarchy Process. The proposed model consists of two basic sections. The first section estimates the importance of selected industries in the countries, whereas the second section evalua...

This work describes the design and realisation of an apparatus to measure simultaneously the AC magnetic properties and the temperature distribution on the top surface of bulk superconducting samples (up to 32 mm in diameter) in cryogenic conditions (temperature range 78-120 K). First the authors describe the experimental set-up used for simultaneous thermal and magnetic characterization of the...

We present a new, efJicient stereo algorithm addressing robust disparity estimation in the presence of occlusions. The algorithm is an adaptive, multi-window scheme using left-right consistency to compute disparity and its associated uncertainty. We demonstrate and discuss performances with both synthetic and real stereo pairs, and show how our results improve on those of closely related techni...
