Extracting a "Dotted Network" skeleton from a glowing raster image for vector editing
#11
good day dear denzjos 

many many thanks for the quick reply. Glad to hear from you. its so awesome  this forum here.

ahhh: note: all (!!!) the above  mentioned examples - they should work only more or less just as examples to get along the way - in other words to learn. 
I am currentliy looking for some examples that may fit here - but well - as you see: i have really my difficulties to find such..



well as mentioned above - i am looking for a really simple example -where i can do some experiments - towards a solution like the following... 


My assumption is to use GIMP to kill the background and Inkscape to trace the dots to vectors. Is there a way to do this purely in one software?

the question here - and the idea i am after is a so called  "Isolation Technique" .. (and below i am trying to explain what is meant here; 


well:  How do I isolate in a example-picture only the brightest: lines/dots  (..without dragging the "the rest" (of the picture) along with them?.....

 - Is it better to work with Layers (e.g., subtracting a blurred layer)?
 - Or is Color Decompose (HSV - Value channel) the standard approach?
 - Are there specific filters (like "Edge Detect" or "Threshold") that preserve the dot structure without making them blobs?

the Question 3: The Vectorization:
 
When using Inkscape's Trace Bitmap, how do I prevent the scattered dots from merging together? Imagine: the original image has distinct nodes, but the glow connects them. How do I tell the software to separate the "nodes" from the "edges"?

Hmm - but dear denzjos, 

it looks like we do not have an appropiate demo that can be used here. 

i am going to look for one ... i am going to surf and try to find some examples - to illustrate what is meant here.


Meanwhile - dear Rich2005 and dear denzjos - many many thanks for your continued support - and your great and generous help. It is really amazing 
and i am so happy to be part of this superb and awesome forum which is a great place for 

a. learing 
b. idea sharing and a awesome example for a 
c. just overwhelming Community of Practice  Heart Smile

thanks for all - i really really hope that lots of others have (also at least)  some benefit form our discussion.


and now i am trying to find som examples.


untill soon. 

greetings. Saint_m Smile
