Face Matching Between Near Infrared and Visible Light Images
In many applications, such as E-Passport and driver’s license, the enrollment of face templates is done using visible light (VIS) face images. Such images are normally acquired in controlled environment where the lighting is approximately frontal. However, Authentication is done in variable lighting conditions. Matching of faces in VIS images taken in different lighting conditions is still a bi...
متن کاملVisible-light and near-infrared face recognition at a distance
A method to solve the problem of face recognition at a distance (FRAD) under the visible-light (VIS) and the near-infrared (NIR) spectra is presented in this work. For images taken under visible light at day time, we perform the coarse-scale alignment/enhancement to eliminate a set of unlikely candidates at the first stage. Then, the fine-scale alignment/enhancement steps are conducted to refin...
متن کاملestimating soil organic carbon using hyperspectral data in visible, near-infrared and shortwave-infrared (vis-nir-swir) range
background and objectives: soil organic carbon is a main soil property and particularly important for development and sustainable management of agricultural systems. soil organic matter content, which is typically measured in the form of soil organic carbon soc content, is commonly regarded as a key indicator of soil quality and utilization (liu et al., 2015). the presence of som has been prove...
متن کاملVisible & Near - Infrared Photometric Analysis
We have re-analyzed archival HST and Subaru data of the recently discovered planetary mass companion (PMC) GQ Lup B. With these we produce the first R and I band photometry of the companion and fit a radius and effective temperature using detailed model atmospheres. We find an effective temperature of 2335 ± 100K, and a radius of 0.38 ± 0.05R⊙ and luminosity of log(L/L⊙) = −2.42 ± 0.07 (at 140p...
متن کاملTunable Visible and Near Infrared Photoswitches.
A class of tunable visible and near-infrared donor-acceptor Stenhouse adduct (DASA) photoswitches were efficiently synthesized in 2 to 4 steps from commercially available starting materials with minimal purification. Using either Meldrum's or barbituric acid "acceptors" in combination with aniline-based "donors" an absorption range spanning from 450 to 750 nm is obtained. Additionally, photoiso...
