How can I "clean" an image sharpened Image?

Hello all. I recently started the openCV library for my C++ project, so I am new to this stuff a little bit. Here is my question...

The Original image: image description

And sharpened Image: image description

If you have noticed, you can see the pixels in the sharpened image. It is like when you apply a color reduction to an image. Is there any way to reverse that color reduction-like effect? Is there any way in openCV to "clean" that image? I don't know if I described myself well :)

You are enhanding edges, so basically adapting the original pixel intensities to have sharper edge info. This does introduce artefacts which are quite hard to get rid of. You could try to binarize this and then map skeleton information on top of the original image for each sign?
