I have a hyperspectral image and I'm trying to perform kernel based PCA in r. I'm not able to produce results. Also I need to export the obtained components to ENVI format. Can any one help me on this?
Hello. I know that there is an ENVI IDL script that does the Kernel PCA. Why don't you try it? One of it is from Kim et al. (2005):
Iterative kernel principal component analysis for image modeling. IEEE Transactions on Pattern Analysis and Machine Intelligence , 27(9): 1351–1366, 2005.
If I got it correct, one of the links below points to the ENVI/IDL scripts.
