I have hyperspectral data cubes of 640*480*100. And want to use patches of my data 16*16*100 as an input for the deeplearning toolbox, but i can't seem to get to get it working. The toolbox only allows image formats, but saving the patches as images isn't possible due to the spectral dimension.

Could you be more specific? The Deep Learning Toolbox is a collection of functions, apps, and examples for designing, training, and analyzing deep learning networks. Which one of these are you having difficulty using?

Hi Cris,

I mean the deep network designer from the toolbox. It only allows jpg, png, etc as input format which consists out of mainly 3 dimensions, r,g,b. But my spectrum consists out of 100 dimensions for the wavelength aspect. I have saved my data in matrices of 16*16*100 but i cant use .mat as an input for the deep network designer

在 MATLAB Online 中打开

but i cant use .mat as an input

Yes, you can.

imds = imageDatastore(location,"ReadFcn",@load);

You also don't necessarily need to keep your input data in files. The input to trainNetwork could be a 16x16x100xN numeric array, assuming you're using a recent enough version of Matlab.
