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 time are big issues in this case. FPGAs are proven to be suitable hardware devices for these types of works. Super resolution involves two parts as global motion estimation and high resolution image reconstruction. In this study, one suitable algorithm, namely as PM, for global motion estimation in the literature is selected to be implemented in real time. On the other hand, for high resolution image reconstruction part, FPGA structures of some well known algorithms in the literature, namely as POCS, MLE, MAP and LMS are proposed and their performance, resource requirements and timing considerations are discussed. Most efficient one is selected and implemented in FPGA.

Real Time FPGA Implementation of Super Resolution for Infrared Cameras
AKTUKMAK, Mehmet; Halıcı, Uğur (2015-08-24)

Therefore, 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.

Analysis and comparison of the contrast enhancement techniques for infrared images
Turan, Arif Ergün; Akar, Gözde; Department of Electrical and Electronics Engineering (2012)
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 loca...
Real-time FPGA firmware for VGA resolution infrared camera
Çevik, Kami; Akın, Tayfun; Department of Electrical and Electronics Engineering (2019)
Infrared cameras generally require pre-processing on raw image data in order to improve the output image quality. Raw output of the infrared cameras occupies a narrow part of the available dynamic range. Contrast enhancement is one of the pre-processing operations and used for improving dynamic range of the low contrast images. This thesis proposes an adaptive histogram equalization method for enhancing the contrast of long wavelength infrared camera output with 640×480 resolution and provides a FPGA implem...
DESIGN STEPS TO TEMPERATURE AND PRESSURE INSENSITIVE OPTICAL SYSTEMS FOR DIGITAL AERIAL IMAGING
Yilmaz, O.; Selimoglu, O.; Ucar, B.; Sengul, O. (2010-10-13)
Imaging from air has evolved from film cameras to digital cameras over the last years. Here we give the design steps of an aerial objective lens for a given CCD sensor. Matching to the pixel pitch of the sensor and providing desired field of view according to CCD size are traditional steps. Besides these, to minimize the environmental effects, design should be insensitive to the temperature and pressure as much as possible. Performance of a lens, designed at room temperature and pressure will be degraded if...
Imaging infrared seeker design
Ünal, Ahmet; Çakır, Serhat; Department of Physics (2014)
The subject of this study is the design of an imaging infrared seeker for aerial targets. Firstly the radiant power of the target was discussed and optical design of seeker lenses were done with ZEMAX Optical Design Software considering the MTF (Modulation Transfer Function) values, optical path ifferences, distortions and detection range calculations. After that, detection range calculations and simulation results of the optical system were presented. Before lock on range calculations, spectral band of the...
