Batch Background Removal

You can automate it quite a bit if you take the photographs with that in mind: good lighting, contrasting and uniform background as a minimum. But in the pictures above, even a human has trouble distinguishing the mannequin from the background.

Otherwise you can offshore the work to sweat shops in Asia, the rates aren't that high and these folks are likely more trained than you, and this can be less expensive than hiring a trained photographer locally to redo the shorts properly.

Hi Ofnuts,  
I want to submit a question;  but I can't find any submit new question button.   I know this is cheating by contacting you here off the subject - but what else could I do?

Hi Ofnots,

Thanks for your help but I feel I am far away from getting this done without your coding help.
I am unable to translate all what is obvious for you pythonwise :-)

Could you please correct this code, knowing that the purpose is to deal with 400 photos and I would like their name to be the same in another file.

PS: my business is very small so I need to use to the max GNU solutions and their generous community;

Thanks again,

Chris

In a Forum page (here your are in a thread, not a forum), there is a big Post thread button.

You are mistaking me for a free script writing service. I write scripts if:

• I learn something in the process
  
• I have some use for it
  
• It can benefit a wide audience
  

None of this seems to apply here.

The Open Source movement works based on mutual benefit. A "generous community" doesn't mean that they do the work and you get the money.

Code:

gimp -idf --batch-interpreter python-fu-eval -b "import sys;sys.path=['.']+sys.path;import batch;batch.eraseBackground('C:/Users/chris/Desktop/CHRIS/MABONNEAMIE/Site/Catalogue/00 Images Produits/00 Images Shooting Originale png')" -b "pdb.gimp_quit(1)

Apprently this piece of code returns an error too but I just changed the name of the script; would you have also any clue?

Thanks a lot,

Chris
