  img2mesh geometry improved

Greeting,

while fiddling with some old ideas I unintentionally managed to improve 
some aspects of my img2mesh Python image to heightfield 3D mesh converter.

You can view the results at the top of img2mesh page, updates section:

https://dnyarri.github.io/img2mesh.html

and download either Python originals or compiled Win10 exe.

In view of recent discussion "I would like to ask the community: do
we really need it?"

I mean new version uses geometry switch based on source local contrast, 
corresponding threshold control is added to program GUI but, obviously, 
it doesn't give real-time preview of final rendering. In theory, I may 
add something like ruby mask preview (like one in Photoshop) for local 
contrast to GUI, but, considering my extremely poor programming skills 
and bad memory, it would be quite time consuming. Surely, I was able to 
make a preview for filtering (you may see it at the bottom of my POV‑Ray 
Thread: Linen and Stitch at

https://dnyarri.github.io/povthread.html#averager

so I can do this, but it wasn't easy.

So, the question is: does anybody really need this img2mesh and stuff?
