Hi everyone,
I tried to implement a code of feature extraction, at first I implemented on dataset pictures with size 77 K for each and its done.
the problem when I changed the dataset pictures with size 2 Mb, its took about two hours for finish.
how can I change the size of the pictures (they are about 60 pictures) and is this affect on feature extraction process?
Thanks for all Regards

Yes, that's true. You can't get a benefit of speeding up by shrinking the image without some tradeoff, like losing resolution. If you just want faster with no drawbacks, then get a faster computer or try to analyze how your algorithm might be speeded up, like reversing the order of nested for loops, or other such things.
