Classify Hyperspectral Images Using Deep Learning

renew:

If you and I encounter the same problem, you only need to install the latest version of matlab to solve it (R2021a+)

i want try the example:‘Classify Hyperspectral Images Using Deep Learning’.

Classify Hyperspectral Images Using Deep Learning - MATLAB & Simulink - MathWorks 中国

but i can't find the help functions:'createImagePatchesFromHypercube' and 'patchesLabeled',although I have installed the 'Image Processing toolbox hyperspectral imaging library',there are not these functions in my computer

Did you try to call this fcn:

openExample('deeplearning_shared/HyperspectralImageClassificationUsingDeepLearningExample')

Have you installed the Image Processing Toolbox Hyperspectral Imaging Library from the Add-On Explorer?

If it is already installed it, make sure it is residing on the search path of your MATLAB. Execute this command:

which createImagePatchesFromHypercube

If you have done it correctly and still you can't find the fcns, then try to reinstall it.

Still it does not work, then you should Contact MathWorks Image Processing Team using the little envelope icon in GUI window.

Thank you for your answer!

1. I have installed the 'Image Processing Toolbox Hyperspectral Imaging Library' from the Add-On Explorer.'openExample('deeplearning_shared/HyperspectralImageClassificationUsingDeepLearningExample')' is not work.'No sample found in this computer.
2. 'which createImagePatchesFromHypercube',The command window shows that'createImagePatchesFromHypercube' was not found.
3. I have reinstalled many times, but the results are all the same.

I just need this function 'createImagePatchesFromHypercube.m' file.If your matlab contains this help function, I sincerely hope you can provide it.

Thank you very much.

@Jiang Karen Which MATLAB version you're using?

"Classify Hyperspectral Images Using Deep Learning" example was introduced in the 20.2.3 version of the Hyperspectral Imaging Library. In order to install 20.2.3 version, you need at least MATLAB R2020b.

It seems like your MATLAB version is older than R2020b.

[Jiang Karen]

my MATLAB version is R2020a
