Searching for the simple counterpart. A function for upsample and sharpen
(not “kron”).

Interpolations is good for up-sampling, but for sharpening it seems likely you’ll want something iterative. If a fixed sharpen
filter is OK then you could upsample and then using ImageFiltering, or you could define custom interpolation “kernels” in Interpolations.
If you put together a package, I’d be interested to see it.
Interpolations?
I haven’t thought about that yet, but many thanks for the tip.I will try it
btw…
Sharping is not so important - only a “nice to have”-option
