I have the following image: https://i.sstatic.net/9g7Bp.jpgimg1

I'm trying to count al these colored cells and draw a circle around them. I really don't now how I can use SelectComponentsSelectComponents for this Imageimage. And edgedetectEdgeDetect has the following result: https://i.sstatic.net/q2jOx.jpgimg2

Maybe some tips or examples.
Greetings
