Workflows

Generate foreground

Generate foreground (RGB + alpha)

If you want more control of getting RGB image and alpha channel mask separately, you can use this workflow.

Blending (FG/BG)

Blending given FG

Blending given BG

Extract FG from Blended + BG

Extract BG from Blended + FG

Forge impl's sanity check sets Stop at to 0.5 to get better quality BG. This workflow might be inferior comparing to other object removal workflows.
