My same solution as in your other post works. Why are you posting a similar question here again?

Please, always provide your IM version and platform when asking questions, since syntax may differ. Also provide your exact command line and if possible your images.

Hi, I apologize in advance if I have breached any rules; I thank you very much for your solution but the problem is that I am trying to detect water mark with different shape and in the solution that you put using some coordinate to obtain the masks ejm 27,27

If all the circles in the watermarks are the same size diameter, then my solution should work. If the circles for the watermarks are different size diameters, then my solution will not work.
