I have a matlab script and its supporting function scripts. my code uses Image processing toolbox. I want to convert all to python. how can I do it ? And my python code should run independent of MATLAB. Any help .

I have used libermate for matlab to python conversion. It is awesome!

I see linux commands but I'm in windows server 2012r2. Are there windows installs too or am I just missing something?
