Infrared image processing systems are used in the beginning only as visualization systems for observation of people and objects in the night or as night vision systems. Next in these systems are included the blocks and algorithms for thermal image processing and these systems became the base of the today’s infrared image processing systems. There are many areas of infrared image processing syst...

This paper presents a concept of image pixel fusion of visual and thermal faces, which can significantly improve the overall performance of a face recognition system. Several factors affect face recognition performance including pose variations, facial expression changes, occlusions, and most importantly illumination changes. So, image pixel fusion of thermal and visual images is a solution to ...

In this paper we do a survey on different fusion techniques of visual and thermal images for human face recognition. Image fusion constructs a single image by combining information from a set of source images together using different techniques. It is quite simpler to extract and locate facial features in visual images. Another advantage of using visual image is that it works well under control...

Monitoring and surveillance are important aspects in modern wireless sensor networks. In applications of wireless sensor networks, it often asks for the sensors to quickly move from the interior of a specified region to the region’s perimeter, so as to form a barrier coverage of the region. The region is usually given as a simple polygon or even a circle. In comparison with the traditional conc...

This study examines and validates a technique for spatial enhancement of thermal satellite images for urban heat island analysis, using a nighttime ASTER satellite image. The technique, termed Emissivity Modulation, enhances the spatial resolution while simultaneously correcting the image derived temperatures for emissivity differences of earth surface materials. A classified image derived from...

I investigated a method for facial expression recognition for a human speaker by using thermal image processing and a speech recognition system. In this study, we improved our speech recognition system to save thermal images at the three timing positions of just before speaking, and just when speaking the phonemes of the first and last vowels. With this method, intentional facial expressions of...

We aim to determine the effect of image restoration (deblurring) on the ability to acquire moving objects detected automatically from long-distance thermal video signals. This is done by first restoring the videos using a blind-deconvolution method developed recently, and then examining its effect on the geometrical features of automatically detected moving objects. Results show that for modern...
