Larger areas

Nicely done Danfeng, thanks for making this available.

Here's a question - you are using VCA as a preliminary (and presumably could use any sort of endmember extraction).

If wanting to do this over a large area this would be problematic - need to be parallelised - e.g. if you had billions of pixels (or more).

Do you think taking endmembers taken from a simpler neural network/ANN that could handle work at such a scale via patching would be a reasonable substitute?

Hi Richard,
Thank you very much for your interest in our work!
Your idea for larger areas is acceptable. You can separately address the spectral unmixing in parallel when facing a large area, e.g., including billions of pixes and more.

Thanks again!
