WebFeb 1, 2024 · Huge data volumes and redundant information are common problems in the field of hyperspectral target recognition. In this study, we propose a method to ensure the accuracy of target recognition while reducing the amount of data, where the effective bands in the hyperspectral data are selected for which the third-order derivative spectrum … WebIt consists in the combination of: 1. a Partial Least Square Regression (PLSR) [27,28] was calculated between the preprocessed derivative spectra and a disease degree, to transform the spectral data into uncorrelated latent variables that provides an invertible matrix for subsequent factorial discriminant analysis.
Derivative analysis of hyperspectral oceanographic data
