Would you explain the formula for me?

I am not the writer of the paper, I am also trying to figure out the problem. But I think “Edge detection by Helmholtz principle” might be helpful. Most of the thoughts of CannyLine came from the paper.

I read this paper recently, I think it means the links between every point in a line.
For example a line with 5point (p1,p2,p3,p4,p5),the possible connection to p1 is(p1,p2,p3,p4,p5),the possible connection to p2 is(p2,p3,p4,p5)... since we set connection without direction, so the sum connection is as formula.
