Hi Wennycham!
The way to get these parameters depends on your use case. If you have trimap or sribbles-image as additional input your best option is to use helper functions closed_form_matting_with_trimap
or closed_form_matting_with_scribbles
, so you don't have to worry about computing prior
and prior_confidence
manually.
closed_form_matting_with_prior
is the most general interface to Closed Form Matting and should be used only if closed_form_matting_with_trimap
and closed_form_matting_with_scribbles
don't suit your use case. In that case prior
is used to set your prior knowledge about alpha matte, prior_confidence
sets per-pixel confidence of that knowledge. Finally, const_mask
is used to exclude from optimization problem those pixels that aren't expected to change, and thus reduce memory usage and computation time.
There is a problem when I use your codes,I don't know how to get these parameters:prior,prior_confidence and optional_const_mask?It would be very kind of you to tell me the method.
