    Abstract : This thesis, within the subfield of computer science known as computer vision, deals with the use of scale-space analysis in early low-level processing of visual information. The main contributions comprise the following five subjects:The formulation of a scale-space theory for discrete signals. READ MORE

  2. 22. Evaluation and Analysis of Supervised Learning Algorithms and Classifiers

    Author : Niklas Lavesson; Sweden Blekinge Institute of Technology School of Engineering Department of Systems and Software Engineering; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; machine learning; evaluation; classification;

    Abstract : The fundamental question studied in this thesis is how to evaluate and analyse supervised learning algorithms and classifiers. As a first step, we analyse current evaluation methods. Each method is described and categorised according to a number of properties. READ MORE

  3. 23. Latency Reduction for Soft Real-Time Traffic using SCTP Multihoming

    Author : Johan Eklund; Anna Brunström; Thomas Dreibholz; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transport protocol; SCTP; multihoming; latency; performance evaluation; failover; concurrent multipath transfer; scheduling; mobility; handover; Computer Science; Datavetenskap;

    Abstract : More and more so-called soft real-time traffic is being sent over IP-based networks. The bursty, data-limited traffic pattern as well as the latency requirements from this traffic present challenges to the traditional communication techniques, designed for bulk traffic without considering latency.

  4. 24. Fault detection in lambda-tuned control loops

    Author : Magnus Berndtsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Abstract : Poorly operating control loops cause loss in productivity in almost every industry worldwide. Therefore performance monitoring has been an active area of research for the past decades. In this work, a newly developed fault detection method is applied to the monitoring of lambda-tuned control loops. READ MORE

  5. 25. Conformal anomaly detection : Detecting abnormal trajectories in surveillance applications

    Author : Rikard Laxhammar; Göran Falkman; Pontus Svenson; Högskolan i Skövde; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anomaly detection; conformal prediction; trajectory analysis; video surveillance; maritime surveillance; Technology; Teknik; Skövde Artificial Intelligence Lab SAIL ; Skövde Artificial Intelligence Lab SAIL ;

    Abstract : Human operators of modern surveillance systems are confronted with an increasing amount of trajectory data from moving objects, such as people, vehicles, vessels, and aircraft. A large majority of these trajectories reflect routine traffic and are uninteresting. READ MORE
