About dataset preprocessing

[4fee8fea]

Dear @likyoo,

I have downloaded the Houston 2013 dataset from the official page.

Equipped with osgeo.gdal and osgeo.gdal_array.DatasetReadAsArray packages, I got HSI.mat and LiDAR.mat just as what's inside the google drive url, just as follows:

from osgeo import gdal
from osgeo.gdal_array import DatasetReadAsArray
HSI = gdal.Open('2013_IEEE_GRSS_DF_Contest_CASI.tif')
HSI = DatasetReadAsArray(HSI)
io.savemat('HSI.mat', {'HSI': HSI})

To my disappointment, these files don't share the same contents.

Could you please tell me how you did the preprocessing step?

Best regards
