Algoritmer för objektdetektering i SAR och IR-bilder / Algorithms for detection of objects in SAR and IR-images

Ahlström, Linus January 2003 (has links)
<p>The first part of the thesis consists of a brief introduction to the general principles of target detection and the sensor-systems used. In the following part there is a theoretical description of the algorithms this thesis focuses on. The detection algorithms described in this paper are called Cell Average, Ordered Statistics, 2parameter and Gammadetector. Two different discriminators called Extended Fractal Features and Quadratic Gamma Discriminator are also described. The algorithms are tested on three different types of data, simulated SAR-pictures, authentic SAR-targets and IR-pictures. The last part account for the results, both those achieved with pictures and those results achieved when doing statistical tests, in this case MonteCarlo- simulations and Reciever Operating Characteristics-curves. The results show that the Gamma- detector and the QGD-algorithm perform best on the tests done in this thesis.</p>

Objektdetektering i SAR- och IR-bilder / Detection of objects in SAR- and IR-pictures

Aronsson, Peter January 2008 (has links)
This report treats detection in IR-pictures taken from airplanes over the ground. The detection is divided in two parts. First there is a detection with filterkernels with the task to point on targets and objects that look like targets. The second part is a discriminator that demands more calculations and has the task to sort out the false alarms from the discriminator. Both the detector and the discriminator contain thresholds thats been trained from trainingsets of data. The results from the detector was better then expected hence it wasn’t possible to test the diskriminator properly. / Den här rapporten behandlar detektering i IR-bilder som är tagna från flygplan över marken. Detekteringen är i det här arbetet uppdelat i två delar. Först görs en detektering med filterkärnor som har till uppgift att peka ut mål och målliknande objekt. Den andra delen är en diskriminator som är något mer beräkningskrävande och har till uppgift att sortera bort de falskmål som detektorn fått med. Både detektorn och diskriminatorn innehåller trösklar som har tränats fram med träningsdata. Detektorn gav bättre resultat än väntat och diskriminatorn har därför inte kunnat testas ordentligt.

Einsatz eines parametrischen Straßenmodells für modellbasierte Detektion und Verfolgung des Straßenrandes mit Hilfe eines Lasermesssystems

Westhues, Andreas 12 June 2005 (has links) (PDF)
Die Arbeit befasst sich mit der Erkennung und Verfolgung von Straßenrandern in unstrukturierten Gebieten. Ein Lasermesssystem detektiert Punkte auf den Straßenr ändern. Mit Hilfe eines Kalman Filters wird der Straßenverlauf geschätzt. Dabei kommt ein vereinfachtes Straßenmodell zum Einsatz.
