I have a very deep understanding of mathematics but have not read so many papers. Has anyone encountered a related problem?
I want to label four corners of four-sided shapes as top-left, top-right, bottom-right and bottom-left. The edges of these shapes are not parallel. It may seem a trivial task to label each corner, but there are shapes which is hard to find each corner. For instance, the following shape shows an example which is easy to be labelled.
On the contrary, I have the following shape which is not easy to find out which corner is which of the mentioned.
I'm aware of the approach which assigns top-left to the min(x+y) and bottom-right to max(x+y) but it is not appropriate due to the fact that I have shapes like the following shape.
I don't know whether there is an approach to label these intersections correctly.
