Dear colleagues,
I would like to kindly ask you for the help with computing a local orientation of Binary line. I have a Binary line in the following image:
I would need to compute a local orientation in degrees for each point of such line skeleton. Other words speaking I need to compute a local orientation distribution in degrees. I do not know how to do that.
I would like to kindly ask you for the help. Thank you very much.

Attach your image here with the frame icon. My corporate security blocked me from visiting your third party site. One way to do it is with find() to get all the coordinates into arrays for x and y and then call
[y, x] = find(skeletonImage);
coefficients = polyfit(x, y, 1);
slope = coefficients(1);
angle = atand(slope);
