In films it is now routine to shoot against
blue (or green) backgrounds, and get absolutely perfect
cut-out masks, such that the cut
out character can be merged into a new background
(with no "blur", "edge" or other artefacts), over 100’s of film frames.
These technique
appear to be fully automated, and not involve
selecting, drawing, "magic wands" etc.
Does anyone know enough about these techniques
to apply them to a simple, single still image,
using standard desktop apps (Gimp, Photoshop,
ImageMagick etc).
