The Fourier filter filters data in the frequency domain to remove unwanted noise and artifacts.
EMSC algorithm for correcting multiplicative/additive effects in spectral data.
This function crops a hyperspectral image by keeping pixels with intensities in a defined range.
Removes Rayleigh and Raman scatter from fluorescence EEM data
The Asymmetric Least Squares performs baseline correction by penalizing positive residuals.
Autoscale standardizes data by centering it to zero mean and scaling it to unit variance.
MATLAB code to align images and hyperspectral images using shift, rotation, and scaling parameters.
Performs PCA filtering on the input matrix, reducing the noise.
Kernelize transforms bilinear data (exponential decays) using kernels to provide trilinear data.
MSC algorithm for correcting multiplicative and additive scatter effects in spectral data.
