Sure, the actual code is in otbPCAImageFilter: https://github.com/orfeotoolbox/OTB/blob/develop/Modules/Filtering/DimensionalityReduction/include/otbPCAImageFilter.h

I tried it with and without normalization. I even performed PCA on the same input images in IDRISI - I got completely different components and matrices with values from 0 to 1. I would like to do this in OTB though. Is there a way to see more specific code with how the rows and columns values of this matrix are calculated? Or get in touch with someone that actually created it? -- -- Check the OTB FAQ at http://www.orfeo-toolbox.org/FAQ.html You received this message because you are subscribed to the Google Groups "otb-users" group.
