Dear Sir

Thanks alot for the code and algorithm,
I applied the algorithm on images but i couldn't save the result, Is there is a way to save the result to work on it ??
Thanks in advance.



respected sir,
Can we use this method in area detection in satellite images?


very good i want to cite your work how to give
