Web10.2.2. Intraband Redundancy and Cross-band Correlation. Hyperspectral applications may exploit the spatial and/or the spectral redundancy to achieve compression. The degree of spatial redundancy within each spectral band would obviously depend on the captured scene. Moreover, while the spatial images of a hyperspectral dataset represent ... Web4.75. To improve the spectral e ciency of amplitude modulation, there exist two basic schemes to either utilize or remove the spectral redundancy: (a)Single-sideband (SSB) modulation, which removes either the LSB or the USB so that for one message signal m(t), there is only a bandwidth of BHz.

WebSep 13, 2024 · Hyperspectral imaging systems are becoming widely used due to their increasing accessibility and their ability to provide detailed spectral responses based on hundreds of spectral bands. However, the resulting hyperspectral images (HSIs) come at the cost of increased storage requirements, increased computational time to process, and … WebMay 30, 2024 · The redundancy and the information content of a band subset are restricted and enhanced by the correlation coefficient and the information divergence (ID), respectively. Subsequently, RRI combines these three indicators as the subset evaluation criterion and utilizes an immune clone selection algorithm to search for the desired band …
WebNeighboring bands in a hyperspectral image have high correlation, which results in spectral redundancy. You can remove the redundant bands by decorrelating the band images. … WebNeighboring bands in a hyperspectral image have high correlation, which results in spectral redundancy. You can remove the redundant bands by decorrelating the band images. Popular approaches for reducing the spectral dimensionality of a data cube include band selection and orthogonal transforms.
WebExploitation of spectral redundancy in cyclostationary signals. It is shown that the cyclostationarity attribute, as it is reflected in the periodicities of (second-order) moments of the signal, can be interpreted in terms of the property that allows generation of spectral lines from the signal by putting it through a (quadratic) nonlinear ...
