Extraction of blue roofs using BRSAM and the newly created spectral index derived from WorldView-2/3 imagery

open access: yesHeliyon, 2022
To extract blue roofs (BRs) from remote sensing images quickly, first, this study used WorldView-2 and WorldView-3 as the data sources and created a new BR spectral area model (BRSAM) using the polygon area difference between the spectral curves of BRs ...

A Statistical and Spectral Model for Representing Noisy Sounds with Short-Time Sinusoids

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
We propose an original model for noise analysis, transformation, and synthesis: the CNSS model. Noisy sounds are represented with short-time sinusoids whose frequencies and phases are random variables.

A tractable framework for estimating and combining spectral source models for audio source separation [PDF]

open access: yes, 2011
The underdetermined blind audio source separation (BSS) problem is often addressed in the time-frequency (TF) domain assuming that each TF point is modeled as an independent random variable with sparse distribution.

Non-destructive monitoring of amylose content in rice by UAV-based hyperspectral images

open access: yesFrontiers in Plant Science, 2022
Amylose content (AC) is an important indicator for rice quality grading. The rapid development of unmanned aerial vehicle (UAV) technology provides rich spectral and spatial information on observed objects, making non-destructive monitoring of crop ...

Spectral Variability in a Multilinear Mixing Model [PDF]

open access: yesIGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
We present a new method for spectral unmixing which takes both nonlinear mixing and spectral variability into account. This is accomplished by combining the multiple endmember spectral mixture analysis (MESMA) approach with the recently developed multilinear mixing model (MLM).
