Hyperspectral imaging is an emerging technology in the field of biomedical engineering which may be used as a non-invasive modality for cancer characterization. In this project, we propose to investigate near-infrared (NIR) hyperspectral imaging for the characterization of canine mammary cancer. Nearinfrared hyperspectral imaging has been used for the detection of various kinds of human cancer;...

Cereal Chem. 76(1):34-37 An optical radiation measurement system was used to measure reflectance spectra of single wheat kernels from 400 to 2,000 nm. Five classes of wheat were used for this study. Three kernel sizes (large, medium, and small) were used to determine how wheat kernel size affects visible and near-infrared (NIR) reflectance spectra and single wheat kernel color classification. M...

Method for vigor diagnosis of tea trees based on nitrogen content in tealeaves relating to NDVI is proposed. In the proposed method, NIR camera images of tealeaves are used for estimation of nitrogen content in tealeaves. The nitrogen content is highly correlated to Theanine (amid acid) content in tealeaves. Theanine rich tealeaves taste good. Therefore, tealeaves quality can be estimated with ...

PURPOSE To investigate the value of multimodal confocal scanning laser ophthalmoscopy (cSLO) for phenotyping fundus lesions in patients with pseudoxanthoma elasticum (PXE) and to correlate these findings with morphologic alterations detected by spectral domain optical coherence tomography (SD-OCT). METHODS Imaging was performed with a combined SD-OCT-cSLO system (Spectralis HRA-OCT; Heidelber...

Visible and near-infrared (Vis-NIR) diffuse reflectance spectroscopy with partial least squares (PLS) regression is a quick, cost-effective, and promising technology for predicting soil properties. The advantage of PLS regression is that all available wavebands can be incorporated in the model, while earlier studies indicate that PLS models include redundant wavelengths, and selecting specific ...

Forest canopy moisture content is an important factor in determining forest fire risk and forest fire behaviour. In Dargon 2 project, to develop a suitable regional early warning technique to predict forest fire risk, a Normal Difference Water Index (NDWI), which has been calculated by using the reflectance of SWIR and NIR band of HJ-1B IRS, has been used to retrieve forest canopy moisture cont...

Visible and near-infrared diffuse reflectance spectroscopy (VIS-NIR) has shown levels of accuracy comparable to conventional laboratory methods for estimating soil properties. Soil chemical and physical properties have been predicted by reflectance spectroscopy successfully on subtropical and temperate soils, whereas soils from tropical agro-forest regions have received less attention, especial...

We report on transparent ZnO/Ag/ZnO and ZnO/Ag/ZnO/Ag/ZnO thin-films were deposited on the glass substrate by RF and DC sputtering for ZnO and Ag targets, respectively. The electrical and optical properties of the single and double Low Emissivity coatings were investigated with respect to the deposition time of Ag mid layer. The visible transmittance remains about 65% for single and 45% for...

The aims of the study were: (i) to compare leaf reflectance in visible (VIS) (400-700 nm), near-infrared (NIR) (740-1140 nm) and short-wave infrared (SWIR) (2000-2400 nm) spectral ranges measured monthly by a contact probe on a single leaf and a stack of five leaves (measurement setup (MS)) of two broadleaved tree species during the vegetative season; and (ii) to test if and how selected vegeta...

Although Near Infrared Analysis (NIRA) as a technique can be traced back to the late 19th century, the first commercial instrumentation (Cary 14) was made available in the mid 1950's. Significant growth in the number of NIRA instruments used did not occur until the 1978-1982 period. During this time, the number of units utilized has grown at an annual compounded growth rate of well over sixty p...
