How can I separate an into groups? - pixaeiro - 12-07-2020
Hello,
Is there any GIMP tool or plugin that can be used to separate an image into groups with the same color?
This is what I'd like to achieve:

I created the layers using the fuzzy selection tool and pasting the selection as a new layer. I'd like to do something like this but with one click... like when using Filter > Enhance > Wavelet-Decompose or Colors > Components > Decompose.
Thank you!

You could try the gimp_gmic_qt plugin. Get the Windows installer from http://www.gmic.eu
Look for the filter Layers -> Colors to Layers and play around with the settings.

Thank you Rick,
This looks very close to what I need, but I'm getting the green and purple in just one layer each, and I need them to be in two different layers.
Imagine that you have an image with green toy soldiers in a white background and you need to count the number of soldiers:
Like this:

I've found that the name of this image processing technique is connected-component labeling, but I can't find a GIMP or G'MIC tool that does this.
Thank you very much for your reply!

I obtained the result of the image above by following the steps below:
01 - Filters - Colors - Indexed Decomposed
Then apply:
02 - Layer - Extract Objects - Extract Objects to Layers (adjust the threshold)

Following the tip of rich2005 the result was much better:
01 - G'micQT - Layers -> Colors to Layers
Then apply:
02 - Layer - Extract Objects - Extract Objects to Layers (adjust the threshold) for layers with more than one color per layer; green and pink.
03 - Erase the initial layers that had two objects per layer.

Hello Krikor,
I found Filters - Colors - Indexed Decomposed as a script-fu (Indexed Decompose)
But I can't find Layer - Extract Objects - Extract Objects. Is this a plugin or script?
Thank you f

Hi pixeiro,
I confess that I didn't know how to answer this question, but I did some research and found that this is one of the great plugins for Ofnuts.
You can find it here:
https://sourceforge.net/projects/gimp-tools/files/scripts/
Bbt I suggest using G'MIC as suggested by rich2005, the result is better and without having to convert to Indexed Mode first.

Hello Krikor,
Yes, I think I have enough info to solve my issues!
Thank you for the Ofnuts scripts link.
