nghiatranduc94 Posted May 18, 2021 Share Posted May 18, 2021 Hi, so I'm working on some setup which will create lines between different color part of a picture. Any suggestion on how to do that? My workflow here is to create a color ramp and change the color of picture to the nearest color in the ramp, then partition by color. But I'm stuck in how to match the color from source picture to the ramp. Quote Link to comment Share on other sites More sharing options...
Librarian Posted May 18, 2021 Share Posted May 18, 2021 (edited) @nghiatranduc94 post some example In picture if you have ...how? (lines surrounding in the area of color , lines connecting like voronoi diagram with diff centers, lines diff like clusters ) ..many ways to do that I think if I understand correctly Edited May 18, 2021 by Librarian Quote Link to comment Share on other sites More sharing options...

konstantin magnus Posted May 19, 2021 Share Posted May 19, 2021 The cluster node, combined with some others, does a good job at vectorizing images: vectorize_image.hiplc 6 Quote Link to comment Share on other sites More sharing options...

vinyvince Posted May 22, 2021 Share Posted May 22, 2021 Nice one Konstantin, thanks Maestro! I gave a try and find using an additional attribute to the cluster k mean , like compute the gradient, help to give better result.

Hi Vincent, that's a lot cleaner! Maybe you could post the updated file, so anyone can learn your methods? Quote Link to comment Share on other sites More sharing options...
vinyvince Posted May 22, 2021 Share Posted May 22, 2021 Im on my ipad now, but oh nothing special, , im computing the gradient of the color, and use this with a high weight in addition to Cd to calculate the Clusters separations See what I mean @konstantin magnus ? ________________________________________________________________ Vincent Thomas (VFX and Art since 1998) Senior Env and Lighting artist & Houdini generalist & Creative Concepts http://fr.linkedin.com/in/vincentthomas Quote Link to comment Share on other sites More sharing options...
