Face recognition using different imaging modalities, particularly infrared imaging sensors, has become an area of growing interest. The use of thermal IR images can improve the performance of face recognition in uncontrolled illumination conditions. In this paper, we present a new technique for face recognition based on statistical calculations of thermal images. We propose the use of moments i...

Staggered time delay and integration (TDI) scanning image acquisition systems are usually employed in low signal-to-noise situations such as thermal imaging. Analysis and restoration of images acquired by thermal staggered TDI sensors in the presence of mechanical vibrations that may cause space-variant image distortions (severe geometric warps and blur) are studied. The relative motion at each...

This paper addresses the problem of detecting and identifying persons with a mobile robot, by sensory fusion of thermal and colour vision information. In the proposed system, people are first detected with a thermal camera, using image analysis techniques to segment the persons in the thermal images. This information is then used to segment the corresponding regions of the colour images, using ...

This article describes four studies conducted through the eViz project, which used a variety of qualitative and quantitative methods, to investigate the impact that thermal images can have on householder retrofit behaviour. Results from thermal image investigations were benchmarked against carbon footprint audit and control cases, and ranged from simple generic letters on energy efficiency to m...

analyses and thermal infrared channels 4 and 5 NOAA- AVHRR images. This research was carried out in Lut Desert located in center of sub-tropical divergence dominant in' Iranian plateau. The physical and thermal properties of the various desert surfaces have been determined using correlation relationships between the desert variables including: dark sand, normal sand, marl, saline soil, soil dep...

The technique of thermal wave thermography combines advantages of both conventional thermal wave measurement and thermography using a commercial IR camera. This technique allows for shorter imaging time and depth profiling. Non-uniformity of heating area and optical surface structures can be suppressed in phase images. Several examples show the potential applications of thermal wave thermograph...

To incorporate the georegistration and restoration processes into airborne data processing in support of U.S. Department of Energy's nuclear emergency response task, we developed an adaptive restoration filter for airborne Daedalus AADS1268 ATM thermal data based on the Wiener filtering theory. Preliminary assessment shows that this filter enhances the detectability of small weak thermal anomal...

Topographical effect was considered in the context of bare soil moisture assessment. Soil moisture was evaluated using thermal inertia modelling. As an input data in thermal inertia model, the images in visible and thermal infrared range are required. Two own programs were worked out modi for thermal inertia modelling and topo – for topographical effect removal. Standard GIS software can have a...
