I am working on a project with big data and I have some trouble to find the nearest path (or cluster) in the data. I'm trying to find the nearest path to the center where a few data can be seen on the excel scatter pilot. I'm just trying to find the distance from the center where the data shows. Another example with the data is heatmap. Area with the no data can be seen on the heatmap as dark blue color. I try to use Reverse K-nearest neighbour algorithm and I also try to do it with RNN-DBSCAN and I couldn't achieve it. Can anyone know how to find that diagonal shape in the center where no data shown?

Thank you for the help.

An example of the shape that I want to find can be seen below. Some of the dots inside the red line will probably be outliers. I want to find the position of the edges on the red line.

Can you mark it in one of your plots? – sehan2 Jul 10 '21 at 20:13
I just uploaded a new picture that I want to find. – Burak Jul 10 '21 at 20:29

Thank you for the help. I need some exact lines and edges so image processing might cause some problem in my project. – Burak Jul 10 '21 at 21:14
