Has anyone done the question of maximum gradients?

jerry__qin

The processed image is a binary image, 1 and 0, 1 is the target pixel, and 0 is the background
All lines are closed or not closed, similar to the contour lines of the map

Now I want to find out where the two lines see the maximum gradient direction, which is the densest direction. How to find it?
