Hi, everyone;
I have some questions below you may have faced previously:
1-I am using an IDL extension for Support Vector Machine (SVM) which
gives out a file with the .tst extension. I can not open the file to
examine the outcomes.
When I try to open it as an image in Envi, it asks me the number of
samples and lines which cause problem when set wrongly.
(I try the same sizes as the original image with 1 band; however, size
is still a problem)
(Basically, I would like to compare original and preprocessed images
classified with supervised methods
with IDL and without any need for a language like Matlab or Java)

2-Additionally, SVM process takes too much time although my image is
resized to be small enough for fast processes;
Is it the regular case or is it a problem that I face?
