I have the following image that I rendered using Blender:
What I want is to remove those black lines (wireframe) but keep the image as smooth as possible. I tried removing them using the Color to Alpha removing the black color and then use a gray layer behind it but that didn’t work.
Is there a way to remove those lines in Gimp?
Answer
Hard to do given the grainy surface:
A first shot is to use a heavy Gaussian (with alpha-lock):
And maybe restore the grainy surface by multiplying with a noise-filled layer:
To be a bit more technical, take the blurred image, set it in Difference mode over the initial image, Layer>New from visible and threshold to get the lines:
You can then use this as a selection (possibly after a Select>Grow), and if you have the Resynthesizer plugin, use Filters>Enhance>Heal Selection:
