Hi there,

These two last days, I've worked quite hard on the G'MIC code (particularly for the GIMP plug-in), and I'd like to share something with you.
This is not yet available in current stable version 1.6.0.0, but it is in current beta 1.6.0.1_beta.

I've added a new filter, named Contours / Extract foreground whose aim is to help extracting a foreground object in an opaque RGB image.
Instead of having to manually draw a selection around the object, with classical selection tools, this filter proposes an alternative approach :
You just have to define control points that can be either labeled 'background' or 'foreground' points. Then, the algorithm tries to automatically
deduce the whole shape of the foreground mask, from the position of the control points and the analysis of the image contours.
I won't enter too much in the algorithm details, but this is intended to save time when doing this tedious selection work.

Here is a video I've recorded to show how the extraction process work (in real-time!).
What you see here is the user adding green and red control points (resp. foreground and background points), and the algorithm is updating its estimated extraction mask.



and two olders (from yesterday :p ) :

This also shows that now, a G'MIC filter in the GIMP plug-in can open interactive windows. This promises good things to come in the future
Hope you'll enjoy this little spoiler !

That's amazing. Cool demos. Wow! Nice job on that girl's hair.

it sounds fantastic!

K1TesseraEna : Background points are set with the right mouse button (or pressing key 'B'), while foreground points are set with the left mouse button (or key 'F').
You can also convert a foreground point to a background point at any time.

I'm really interested by your feedback if you have some time to test !

Cool stuff David. Very much looking forward to this feature when samj releases her next build.

And to K1Te; you Ninja's me.

Yes, k1, please post here, I'll try to look at this thread regularly.

Which version of the beta did you take ? If older than yesterday, it can't work.
Is it one compiled by Samj ? I don't think she's already compiled the very latest version yet.

This one gmic_gimp_1.6.0.1_beta_win32 - marked >2 hours ago
no it's not samj's, from the SF

Ha ok, so could you post a link to your image somewhere, i'd like to be able to reproduce the bug.

Also, please try to refresh your filters again, I've done recent changes that must improve the whole thing (hopefully :p).

That's incredible my friend.

I've just moved the filter to *Contours / Extract foreground*, that may explain why you don't see it anymore
(was in *Testing / Ronounours / * before..).

EDIT : I've just tested with your image, works like a charm

Haaaa, finally ! :p
