What filter should be used for the XYZ plot?

Question

data mining

Hello, I have a question about filtering a 3d graph with noise and emissions.
There is an image where you need to know the coordinates of the red dots, but they can be very close.

Or


I decided to start with a double array of values ​​for how much each point (pixel) is close to red.
And I got a 3d graph that looks like this in a section.
As an example.


What filter do I need to apply so that as a result the graph looks like smoothed peaks. So that I could determine the coordinates of the heights from the vertices.
Like something like this.


Thanks in advance for your constructive response.

Answer 1

moving average

Answer 2

The simplest thing is to process the neighborhoods of each of the points, and then take either the average, or the average with the extreme values ​​\u200b\u200bthrown out, or something else
