For example given a big set of random points, and I extract a small section of the random set of points, how can I find the small set on the big set?
As a first approach I tried to do a Delaunay triangulation, on the random points and then on the small set of points and the compare both the images, but is there any image pattern recognition in Mathematica?
As a first approach I construct a Delaunay mesh in the whole set, and then in the extracted part of the image create again the triangular mesh and then try to compare them. But I don not know how to do it. Here is the link of the code fore the mesh: How can select a specific triangle in my Delaunay mesh?
