I was wondering if anyone in this forum has ever used ITK/SimpleITK to register hyper spectral satellite imagery. Any advice is very welcome!

Hello @Arrigo_Benedetti,
Haven’t done any remote sensing image analysis myself, but am aware of the [Orfeo Toolbox](https://www.orfeo-toolbox.org/), a remote sensing toolkit built on top of ITK. Potentially that domain specific tool is more relevant than the generic tools, SimpleITK/ITK?

I’ve registered RGB satellite imagery with [Mattes Mutual Information](https://itk.org/Doxygen/html/classitk_1_1MattesMutualInformationImageToImageMetric.html) which gives you some robustness to domain shifts between images. Though I think it may become pretty expensive as you increase the number of bands. I believe that even in the RGB case, I may have solely registered a grayscale representation of the data.

@david.russell thanks for the feedback!
