Semantic segmentation is a machine learning task that seeing increased utilization in multiple fields, from medical imagery to land demarcation and autonomous vehicles. A real-time system must be lightweight while maintaining reasonable accuracy. This research focuses on leveraging the fusion of long-wave infrared (LWIR) with visual spectrum fill inherent performance gaps when using alone. appr...

In modern thermal infrared applications, multi-spectral camouflage scenarios should be developed to mitigate the signature of an object. general, needs satisfied in two main optical ranges: visible, and (IR). IR range, camera modes are deployed detect object: i) short-wave (SWIR) cameras that solar photons reflected off a surface, ii) mid-wave (MWIR) long-wave (LWIR) directly collect blackbody ...

Wildland fire radiant energy emission is one of the onlymeasurements of combustion that can bemade at wide spatial extents and high temporal and spatial resolutions. Furthermore, spatially and temporally explicit measurements are critical for making inferences about fire effects and useful for examining patterns of fire spread. In this study we describe our methods for capturing and analysing s...

Resupplying forward-deployed units in rugged terrain in the presence of hostile forces creates a high threat to manned air and ground vehicles. An autonomous unmanned ground vehicle (UGV) capable of navigating stealthily at night in offroad and on-road terrain could significantly increase the safety and success rate of such resupply missions for warfighters. Passive night-time perception of ter...

A physics based 3D simulation of sea surfaces is presented. The simulation is suitable for the pre-calculation of detector images for an IR camera. Synthetic views of a maritime scenario are calculated in the MWIR and LWIR spectral bands and the images are compared with data collected in a field trial. In our computer simulation the basic sea surface geometry is modeled by a composition of smoo...

This paper presents and discusses digital pixel readout integrated circuit architectures for long wavelength infrared (LWIR) in CMOS technology. Presented architectures are designed for scanning and staring arrays type detectors respectively. For scanning arrays, digital time delay integration (TDI) is implemented on 8 pixels with sampling rate up to 3 using CMOS 180nm technology. Input referre...

The in-scene atmospheric compensation (ISAC) algorithm of Young et al. (2002) [14] (and as implemented in the ENVI software system [16] as ‘Thermal Atm Correction’) is commonly applied to thermal infrared multiand hyperspectral imagery (MSI and HSI, respectively). ISAC estimates atmospheric transmissivity and upwelling radiance using only the scene data. The ISAC-derived transmissivity and upwe...
