Does it have to exactly replicate the image or just be similar?

Your photo is very similar to a 2d voronoi pattern. If it is an acceptable option to you, I would take the centroid of each blob (using the area component) and input those into a voronoi 2d component. The borders of the voronoi cells will be pretty close to the black likes you drew (not exactly, but hopefully close enough for you).

Hi Brian,

Thanks a lot for the answer!

I tried your approach, but another important issue is that I want "continues" gaps to remain as much as possible continues - in the attached image you can see the Voronoi result (black) and my desired result (white).

Thanks again,

Does someone have any idea..?

Provided you don't mind a slow calculation and slightly jagged edges at a small scale, this method will suit you:
