Parallel implementation of algorithms for standoff detection in hyperspectral imagery
Hyperspectral imaging systems, used in conjunction with appropriate detection and recognition algorithms, have demonstrated to be very appropriate tools for standoff detection in many different environments. Compared to other techniques available such as multispectral imaging, which typically collects only tens of images, hyperspectral instruments are capable of collecting hundreds of images, c...
متن کاملAcoustic-Laser Vibrometry for Standoff Detection of Defects in Materials
Standoff methods of non-destructive testing (NDT) offer flexibility over traditional methods of inspection which typically require physical contact with the material being measured. The benefits are that difficult to access locations can be inspected and measurements of a large area can be made more quickly. Acoustic-laser vibrometry is a robust standoff NDT technique for composite materials, s...
متن کاملAnalysis of Hyperspectral Imagery for Oil Spill Detection Using SAM Unmixing Algorithm Techniques
Oil spill is one of major marine environmental challenges. The main impacts of this phenomenon are preventing light transmission into the deep water and oxygen absorption, which can disturb the photosynthesis process of water plants. In this research, we utilize SpecTIR airborne sensor data to extract and classify oils spill for the Gulf of Mexico Deepwater Horizon (DWH) happened in 2010. For t...
متن کاملA Solid-State Hyperspectral Imager for Real-time Standoff Explosives Detection using Shortwave Infrared Imaging
We present a new and innovative short-wave infrared (SWIR) hyperspectral imaging focal plane array (FPA) concept for bulk and trace standoff explosives detection. The proposed technology combines conventional uncooled InGaAs based SWIR imaging with the wavelength selectivity of a monolithically integrated solid-state Fabry-Perot interferometer. Each pixel of the array consists of a group of sub...
متن کاملUltraviolet Raman Wide-Field Hyperspectral Imaging Spectrometer for Standoff Trace Explosive Detection.
We constructed the first deep ultraviolet (UV) Raman standoff wide-field imaging spectrometer. Our novel deep UV imaging spectrometer utilizes a photonic crystal to select Raman spectral regions for detection. The photonic crystal is composed of highly charged, monodisperse 35.5 ± 2.9 nm silica nanoparticles that self-assemble in solution to produce a face centered cubic crystalline colloidal a...
