A script or plugin to remove backgrounds

I don´t get why path tool is so popular for bg extraction, polygonal selection tool is easier and faster imho.

If You´re searching for a free solution, You could try GML matting 0.3 with PSPI plugin. You can still find GML matting free version online. The new shareware version is called GrowCut.
Can´t guarantee compatibility with Gimp though, have used it with older version of Photoshop only.

ShellOut + Vertus Fluid Mask is unbeatable combination for complex extraction.

I use GrowCut and it does work with my Gimp-2.8.4.
I have not tried in Gimp-2.8.7 yet.

Not that popular really. But it's unbeatable for man-made objects so professionals use it a lot.

Actually i like using RGGJAN's FG select tool more than GrowCut. It's way easier, and faster to get nice results.
I was real happy to see Onkel include it with his Gimp-2.8.7 build.

Thank you Onkel.

Installed Growcut, but can't find it once I open GIMP.

Never mind. I installed a version that no longer works, apparently.

You need to install the plugin and set a PATH with PSPI. (Filters>Photoshop-Plugin-Settings)
After install you will find it under Filters>iPhotosoft>GrowCut
A window will open for your reg key info.Add that and restart GrowCut.

Remember GrowCut only works on images with an alpha channel.

GML Matting is an older version of GrowCut and after install will be located here
Filters>GML>GML Matting and needs an alpha channel to work also.

I attached the exe in a zip for you.

It will install auto to program files and give you a check box for other. Select other and install where your photoshop 8BF files are located for GIMP.
OR install in XnView plugins folder and use shellout.

Both GrowCut and GNL Matting work in Gimp-2.8.4 (Parthas installed build)

you cant change the nodes of the lasso tool after you clicked

what i dislike about the path Tool in Gimp is that the nodes have become too big
i think they changed that in 2.8
the nodes were smaller in 2.6 if i remember correctly

I understand, I have several Photoshop plugins installed. I found what looked to be a free version, but it didn't work at all. I downloaded the trial version, and it works fine. I also have had GML Matting. Thanks for the heads up anywhos, appreciate it.

I hear you. I wish there were a way to make those nodes smaller also. :bigthup

you can change (move around) any node of the lasso tool until the moment you close the loop to
make a selection.
