Playing today for the first time with G'mic SKIN MASK by Iain Fergusson.
I've found it very interesting, because parametric on colours to adapt it to the source image.
Any plan to improve it further?
Or to add parameters on colours in "Detect Skin" by David?

Tried to use today Peiodic Dots, using defaults.
Got this error:



G'MIC 2.9.4 on Gimp 2.10.23 Samj

edit: it happens also on G'MIC 2.9.5pre december

Possible GMIC filter error in Artistic/hough sketch?

I encountered this problem, while doing some tests:

case A:
1.open an image
2.apply GMIC/Artistic/Hough Sketch (I use output on new active layer)
3.result OK. evident sketching lines on the image

case B:
1.open an image
2.add a frame using GMIC/Frames (blur)
3.result OK, image framed
4.apply GMIC/Artistic/Hough Sketch (I use output on new active layer)
5.result not OK. an almost totally white layer

It seems that Hough Sketch does not work properly on a frames image.

Can someone verify?

My environment:
- Winfows 10 up to date (my hardware does not support Windows 11)
- GIMP 2.10.32 (samj's pack)
- GMIC 3.2.4

Original image:

Output case A:

Output case B:

I can confirm this on:
Linux Mint 20.1
GIMP 2.10.34 PPA
GMIC 3.2.2

Thought it's a matter of alpha channel for that layer, but it does not make a difference if the layer has one or not.

Yep, I can reproduce that as well - kubuntu 20.04 / Gimp 2.10.34 / gmic 3.2.4

A couple of tests. Not alpha. not precision, not multiple layers.

It is the border, isolate with a selection inside the border and Hough Sketch works (although it leaves transparency as a border)

Yes, Rich, same solution I did find.
But, isn't it an error? Either in the Frame filter or in the Hough Sketch?

I would think it is an error. Best place to get Davids attention is https://discuss.pixls.us/tag/gmic

Ditto here.

hough, upon whichfx_houghsketchbw is based, embodies a voting scheme. hough's orthodox use is to find alignments within images. The strange looking exemplar on the right hand end of the example in the technical reference encodes a voting tally where line segments of particular orientations and positions gain prominence and appear lighter in the voting tally. fx_houghsketchbw scans this tally and plots the line segments that garner the greater balances in the tabulation.
On the one hand, I am inclined to think that the frame so dominates this tally that it swamps other candidates, but on the other, I think the 'vote' shouldn't be that one-sided. `Tis early Sunday morning here on the eastern seaboard of North America. Dawn is breaking. There is time for extra coffee on days such as this and contemplation of things G'MIC. I happen to be preoccupied with Hough-like ruminations at present. Let us add this one to the pile.

I also do agree with you. We also need this kind of forum for proper interaction!

For Linux users only GEGL in Gimp will soon be able to call GMIC strings using the version of GMIC installed on the user's system using this plugin.

This will be automatable using GEGL Graph syntax to chain GEGL and GMIC filters together and in theory I can make GEGL plugins that depend on Linux and the system's GMIC to work.

viewtopic.php?f=9&t=20652

Any Youtube tutorial that involves GMIC and Gimp together may end up automated with GEGL syntax. Such as a few popular youtube tutorials for Gimp that involve GEGL and GMIC together for things like a cartoon or painting effect, that will be transformed into a line of automatable syntax. This will also open a whole new window of text styling possibilities that I was never able to automate before.

Once again this plugin is Linux only because it depends on bash (something that is unique to Linux and not on Windows) if we get support which is doubtful their could be a Windows counterpart to the plugin called gegl powershell. Which is Window's counterpart to bash.

How to install bash on windows 10?
Installation Of Bash Shell On Windows Is Native as they wrote > https://hackernoon.com/how-to-install-b ... -is-native
The above link explain how to install bash on Windows, and it's quite easy IMHO (although I don't use Windows, but by reading the steps, it looks very easy)

I guess in the near future if Liam figures out how to do it we could have a Windows version. But right now the initial release of GEGL Bash will be Linux only. We don't have a Windows 10 machine to test on.

Also I should point this out that the plugin is meant to be used in GEGL Graph syntax not in a GUI.
