Today, infrared cameras are used especially for target tracking and surveillance operations. However, they have a high dynamic range output, and the standard display devices cannot handle them. In order to show them on common devices, the dynamic range is cropped. Thus, the contrast of the image is reduced. This is called as the High Dynamic Range (HDR) Compression. Although several algorithms have been proposed for preserving details during the HDR compression process, it cannot be used to enhance the local contrasts of image contents. In this thesis, we compare the performances of contrast enhancement techniques, which are suitable for real time applications. The methods experimented are generally histogram based methods. Some modifications are also proposed in order to reduce computational complexity of the process. Performances of these methods are compared with common objective quality metrics on different image sets.

Dim point target tracking in infrared image sequences with low SNR
Güler, Zahide Selin; Vural, Elif; Department of Electrical and Electronics Engineering (2016)
Dim point target tracking in infrared (IR) images has been an active research area especially in military fields. Due to the long distance from IR sensors, target appears as a dim moving point hidden in a heavily cluttered background and causes the Signal to Noise Ratio (SNR) to be very low. We present a tracking algorithm based on Particle Filters (PF), which estimates the target position by using both brightness level and motion model measurements. A target candidate list for the presented PF algorithm is...
Characterization of a terahertz wave scanned imaging system for threat detection at standoff distances
YILDIRIM, İBRAHİM SONER; ÖZKAN, VEDAT ALİ; Idikut, Firat; Takan, Taylan; ŞAHİN, ASAF BEHZAT; Altan, Hakan (2016-07-01)
A terahertz active scanned imaging system is developed in order to acquire images of various targets at stand-off distances. The images are analyzed with respect to the experimentally obtained beam profile at the target plane using a commercially available mm-wave/terahertz camera. The active scanning system utilizes a heterodyne, continuous wave transceiver unit operating at 340 GHz and 2-D opto-mechanical scanning of the target plane is performed using two large area mirror coupled galvanometers. 340 GHz ...
FPGA implementation of real time digital video super resolution for infrared cameras
Aktukmak, Mehmet; Halıcı, Uğur; Department of Electrical and Electronics Engineering (2013)
At present, the quality of image taken from infrared cameras is low compared to the other cameras because of manufacturing technology. So, resolution enhancement processes are becoming more important for these cameras. Super resolution is a good approach to solve this resolution problem. In general, the systems that infrared cameras used require video processing to perform in real time. So, a suitable approach should be selected and implemented to work in real time. The computational load and processing tim...
Surveillance wireless sensor networks: Deployment quality analysis
Onur, Ertan; Delic, Hakan; Akarun, Lale (2007-11-01)
Surveillance wireless sensor networks are deployed at perimeter or border locations to detect unauthorized intrusions. For deterministic deployment of sensors, the quality of deployment can be determined sufficiently by analysis in advance of deployment. However, when random deployment is required, determining the deployment quality becomes challenging. To assess the quality of sensor deployment, appropriate measures can be employed that reveal the weaknesses in the coverage of SWSNs with respect to the suc...
Infrared low observable material design, synthesis and characterization
Keskin, Ahmet; Ünalan, Hüsnü Emrah; Bek, Alpan; Department of Metallurgical and Materials Engineering (2023-1-27)
In recent years, infrared low-observable technology has come to the fore in the aerospace and defense industry to conceal military aircraft against rapidly developing infrared search and tracking systems. Pigment materials developed for coatings applied to aircraft surfaces based on materials science and engineering in line with electromagnetic principles play a crucial role in this regard. Although low-observable structures were obtained in the 8-14 µm infrared wavelength range in particle studies, radar a...
