I have an image and I already get the boundary and the weighted centroid of region of interest. I want to get the coordinate point of boundary at certain degrees. It starts from coordinate point at 0 degree from centroid point(blue colour in image)a,d its counterclockwise. Can anyone help me about this? Thx for the help

Calculate the angle of every point using atan2d() then use both returned values from min() to find which one is closest to the angle you're looking for. Let me know if you can't figure it out from those instructions. It's like 2 lines if you vectorize it.
