  2. 1. 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

  4. 2. Assessment of Aircraft Radar Cross-Section for Detection Analysis

    Author : Björn Persson; Ulf Ringertz; Martin Norsell; Peter Bull; João Tasso de Figueiredo Borges de Sousa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flyg- och rymdteknik; Aerospace Engineering; Försvarssystem;

    Abstract : Hiding from and surprising an opponent are tactics that have been used in warfare throughout history. They were features that aircraft originally possessed when they were first used in military operations. However, development of military technology is an endless struggle between advances in technology and counter technology. READ MORE

  5. 3. Anomaly detection in trajectory data for surveillance applications

    Author : Rikard Laxhammar; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Anomaly detection; trajectory analysis; statistical methods; conformal prediction; automated surveillance; Computer science; Datavetenskap; Datalogi; Computer and Systems Science; Teknik;

    Abstract : Abnormal behaviour may indicate important objects and events in a wide variety of domains. One such domain is intelligence and surveillance, where there is a clear trend towards more and more advanced sensor systems producing huge amounts of trajectory data from moving objects, such as people, vehicles, vessels and aircraft.

  6. 4. Model-Based Stem Volume Retrieval and Windthrow Detection using CARABAS and P-band SAR

    Author : Klas Folkesson; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CARABAS; remote sensing; forest monitoring; model-based stem volume retrieval; image segmentation; synthetic aperture radar SAR ; P-band; windthrow detection;

    Abstract : Radar remote sensing is an efficient method for monitoring forests over large areas. Radar waves transmitted from a system carried by a satellite or an aircraft interact with trees on the ground, and the reflected waves are used to form images which are independent of weather and light conditions.

  7. 5. Increasing Autonomy of Unmanned Aircraft Systems Through the Use of Imaging Sensors

    Author : Piotr Rudol; Andrzej Szalas; Pascual Campoy; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; UAV; UAS; UAV autonomy; human-body detection; color-thermal image fusion; vehicle tracking; geolocation; UAV indoor navigation;

    Abstract : The range of missions performed by Unmanned Aircraft Systems (UAS) has been steadily growing in the past decades thanks to continued development in several disciplines. The goal of increasing the autonomy of UAS's is widening the range of tasks which can be carried out without, or with minimal, external help. READ MORE
