 I have used a multiscale technique above BUT you said you couldn't use .shape.

The code you show doesn't do multiscale as far as I can see.
sorry it was the wrong code... i se it now.

 Hi,
You can use cython to compile your python code "file.py" to library "file.so" that you can import in your main python program. I use this method last year and it works.
Can you tell me how to compile it with cython? what do i need to do with the code?
