* add a layer mask to the initial image, using the selection to initialize the mask
* alpha-select the result (IIRC, gimp_select_item() the layer) * apply color-color-alpha and remove the white * increase contrast and tweak the brightness so that everything you want to remove is white. The old Color-to-alpha (the one you can use via Python-fu) has no Transparency/Opacity thresholds, but I don't think it matters much in your case. Sorry my knowledge is poor in gimp and Puthonįilters>Python-fu>Console, and hit the Browse button. Thanks Ofnuts for this resource but where can I find the command that creates the action of getting color tonalphaband then setting Opacity and Transparency thresold ? Thanks Ritergeek for your answer! As I did not know it I made a Bimp on it -) took ages -) The switch is in Preferences>Image Import & Export >Import Policies. Now you can set GIMP to automatically add an alpha channel to jpg images. Have you tried right-clicking your base image and adding an alpha channel? JPG images did not load with an alpha channel until 2.10.10, which released a few days ago.

Would you have such a code that I could adapt to the file where I have 500 pictures to handle ?
#GIMP REMOVE WHITE BACKGROUND CODE#
➤ I am missing the code though to batch process it as the Bimp in Gimp does not offer to deal with those functionality. I have discovered that the "alfa to color" function with Threshold and Opacity set to 50% create a realy good job even in complicated background! Yes I believe in automation -) and I want to be autonomous on this matter if possible
Thanks a lot Ofnuts for your swift answer proving Gimp is a real alternative PS: with that link above, it looks like I'm spamming my own forum 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. But in the pictures above, even a human has trouble distinguishing the mannequin from the background. 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.
