Hyper-Spectral Sensor Calibration Extrapolated from Multi-Spectral Measurements
Hyper-spectral (HS) sensors are the instruments of choice for remote sensing applications involving environmental monitoring, littoral survey, and military assessment. Accurate band-to-band sensor radiometric calibration is critical for successful data mining of such HS spectral sets. Current …

High field terahertz radiation : conduits to synchronized hyper spectral systems
… up the possibility of highly synchronized multi-spectral systems to transform the landscape of scientific investigation and medicine among others. In this thesis, the problem of efficient conversion is tackled theoretically. A montage of novel computational techniques, analyses, device proposals …

An Investigation Of Sub-Pixel Cloud/clear-Sky Contamination Using Hyper-Spectral AVIRIS Data
… over the west coast of Northern California. The hyper-spectral data from AVIRIS have a spatial resolution on the order of 11.5 m for the study case, thus can be used for carefully examining the sub pixel cloud related bias in GOES data. This study suggest that significant sub-pixel cloud and …

Framework for Automatic Identification of Paper Watermarks with Chain Codes
… the recently acquired watermarks digitized with hyper-spectral imaging of Summa Theologica, the work of Antonino Pierozzi (1389 – 1459). The performance of the algorithm on large datasets is demonstrated using watermarks datasets from well-known library catalogue collections.

Computed Tomographic Imaging Spectrometry
… is an imaging spectrometer which can acquire a hyper-spectral data set in a single snapshot (one focal plane array integration time) with no moving parts. A specially designed dispersing element, which separates light from the three-dimensional object cube into a grid of two-dimensional …

Improved uncertainty estimates for geophysical parameter retrieval
… like AIRS/AMSU, as well as a hypothetical future hyper- spectral microwave sounder. Mixture density networks (MDN) and Sparse Pseudo Input Gaussian processes (SPGP) were found to be the most accurate at variance prediction. Both of these are novel methods in the field of remote sensing. MDNs also …

Development of optical systems and imaging analyses for hyperspectral microscopy and 3D super-resolution imaging
… factors greater than conventional microscopy. Spectral imaging techniques have been developed towards generating hyper-spectral movies at 30 frames per second. Many new techniques are in development to meet the growing demand for better biological information. In this work, we first demonstrate …

Characterization of inducible antibiotic production by streptomycetes isolated from hyper-arid environments
… locations. Furthermore, phenotypic analysis and hyper-spectral imaging revealed hidden diversity of the isolates. Whole-genome analysis contradicted the phylogenetic relationship observed using 16S rRNA. Unique inter and intraspecific variations between isolates emerged with two distinct clades …

Learning sparse representation for image signals
… (LVQ). The learned dictionary is applied to hyper-spectral image classification, with additional spatial neighborhood information incorporated using a probabilistic formulation. To better understand the rationale of SRC, we further develop a margin-based perspective into the classifier. The …

Deriving bathymetry from multispectral and hyperspectral imagery
… Bathymetry from remote sensing with multispectral or hyperspectral imagery provides an opportunity to acquire water depth data faster than traditional hydrographic survey methods without the need to deploy a hydrographic survey vessel. It also provides a means of collecting bathymetric …

Phenotypic consequences of adaptive toxin production and resistance in coevolutionary partners
… two color-capture methods (spectrometry and hyper-spectral imaging), we found support for a model of qualitative honesty but did not find quantitative honesty in the form of correlation between any colorimetric and toxin level at either the intra- or interpopulation level for either species. …

Improving Soil Moisture Assessment of Turfgrass Systems Utilizing Field Radiometry
… influenced by water absorption within a narrow spectral range of near-infrared light. Previous research has established strong relationships between moisture stress of creeping bentgrass (CBG) grown on sand-based root zones, a typical scenario for golf course putting greens. However, this …
