Question

I have some geological points with following distribution:

I need an algorithm to filter desultory/single points and to group points which are adjacent.
I require the algorithm create something like the following from above points for me

So after applying algorithm on first figure, I need three conglomerate of points, each one known as a critical section, be generated. (like figure 2)

I know some algorithms including Graph Partition, Convex Hull, Polygon Partitioning algorithms, but no one is typically suitable for this problem.

Do you know any specified algorithm for this question?

Answer 1

Look like a typical example case for density based clustering to me.

Look up DBSCAN on Wikipedia.
