Comparison of the Inversion Periods for Mid-wave IR (MidIR) and Long-wave IR (LWIR) Polarimetric and Conventional Thermal Imagery

Mid-wave IR face recognition systems

Today’s military threats are different from those of the recent past. The organizations and skills necessary to develop efficient operations against such threats are not the same as even 10 years ago. The present-day army requires diverse capabilities to operate in the modern combat environment, and one of the high-demand skills of soldiers is the ability to detect and track humans as well as i...

Illumination Invariant Face Recognition Using Thermal Infrared Imagery

A key problem for face recognition has been accurate identification under variable illumination conditions. Conventional video cameras sense reflected light so that image grayvalues are a product of both intrinsic skin reflectivity and external incident illumination, thus obfuscating the intrinsic reflectivity of skin. Thermal emission from skin, on the other hand, is an intrinsic measurement t...

Long-Wave Infrared (LWIR) Polarimetric and Radiometric Analysis for a Variety of Thermal and Electromagnetic Suppressing Materials

Long-wave infrared imaging of vegetation for detecting leaking CO2 gas

The commercial development of uncooled-microbolometer, long-wave infrared (LWIR) imagers, combined with advanced radiometric calibration methods developed at Montana State University, has led to new uses of thermal imagery in remote sensing applications. One specific novel use of these calibrated imagers is imaging of vegetation for CO2 gas leak detection. During a four-week period in the summe...

Flood-survivors detection using IR imagery on an autonomous drone

In the search and rescue efforts soon after disaster such as floods, the time critical activities of survivor detection and localization can be solved by using thermal long-wave infrared (LWIR) cameras which are more robust to illumination and background textures than visual cameras. This particular problem is especially challenging due to the limited computational power available on-board comm...
