A Whittaker smoother using penalized LS & iterative imputation to smooth data & fill gaps.
Removes cosmic peaks from spectral data via derivative thresholding and interpolation.
Dynamic Time Warping and Correlation Optimized Warping for signal alignment
This code recovers saturated signals using O-ALS by treating saturated signal as NaNs and reconstructing them from PCA subspace.
The WienerFiltering function denoises data using Wiener filtering based on Welch's PSD estimation.
Smooths each row of the input data (or computes its derivatives) using a Savitzky-Golay filter.
This function crops a hyperspectral image by keeping pixels with intensities in a defined range.
Applies the Whittaker smoother using penalized least squares to reduce noise.
MATLAB code to align images and hyperspectral images using shift, rotation, and scaling parameters.
EMSC algorithm for correcting multiplicative/additive effects in spectral data.
