How to find coordinates of all maxima for 3 coordinates?

Question

Mathematics

Hello, I have a simple question.
How to find the coordinates of the vertices (peaks) for a 3D graph?
Describe the algorithm please.

1. The peaks have different heights.
   
2. They can climb with their bases on top of each other.
   
3. Peaks have different base angles.
   

Of course, there are no graph formulas, there is data.
As an example, several images of similar graphs.






Thank you in advance for your response.

If the data is given in an array, you need to iterate through it and find all the maximums. If you have an area as a maximum, you can take its center
