Ubuntu – Software to automatically remove background from images

image processingsoftware-recommendation

Are there any Ubuntu alternatives to photoscissors, which makes it easy to remove the background of an image?

I'm currently using GIMP in different ways to do the same but for some images it takes a long time.

The imagemagick package includes a convert command.

Example commands:

convert image1.jpg -fuzz 20%% -transparent White image2.png
convert image1.png -threshold 10%% image2.png

Both are simple versions of removing a background and might make all other none-background white in the image transparent (the fuzzy/threshold options can adjust that).

But Imagemagick has examples on removing backgrounds using masks.

What works best depends on the original. JPG tend to be fuzzy (what looks like the same color often are slightly different colors) so they will have mixed results.
