Someone could help me understand how I can use the pca of Laurens van der Maaten in matlab. The toolbox is in link I have the toolbox installed in matlab I have the hyperspectral image indian Pines leida
but how to use PCA for me to be able to identify the bands that do not serve me as those that have a lot of noise and are useless? in the help says
coeff = pca (X)
After reading the hyperspectral image, the dimensions are 145x145x200
Where it contains 200 bands but how can I use PCA for me to be able to identify the main components and the other rest of bands like the noisy ones using the graphic to visualize each band
I need to use figure (graph with imshow or imagesc) to visualize each band and see which ones are very noisy and then remove them
