Hello.
I am currently trying to automize a flow to detect drawn graphite lines on paper. I decided to use edge detection for the job, and after alot of experimentation, i found that Edge detection -> difference of gaussians, with radius1 = 4.872, and radius2=0.533 was just perfect.
The gimp procedural database contains a difference of gaussians (dog) plugin: plug-in-dog(image,drawable,inner,outer,normalize,invert)
Already here we can some differences: no longer are the parameters simply "radius1" and "radius2", but specifically "inner" and "outer". Also, the "normalize" bool-option is nowhere to be found when applying the filter directly from gimp.
More importantly though, this plug-in simply gives different results! And quite alot worse too unfortunately. Not good enough for what i'm trying to do atleast.
Why would the script in the procedural database be different? Does this have anything to do with the shift to GEGL in 2.10 (I don't actually fully understand what that means, other than it having something to do with the ways graphics are dealth with, and most likely being better).
Is there any way i can acess the filter actually used by gimp?
Have a nice day!
