Recalculate binary line local orientation
显示 更早的评论
Dear colleagues,
I would like to kindly ask you for the help with computing a local orientation (angles distribution) of a binary curve in each pixel of its skeleton.
I am using the function SkeletonOrientation, which is attached. This function calculates this orientation with using the function: regionprops(), with the attribute: Orientation.
Unfortunately, this function calculates angles in the range: -90°- 90°, but I need to have this range withing -180° - 180°. I did not find any alternative in MATLAB to do that. Thus, I would like to kindly ask you how to recalculate this angle’s range.
Thank you very much.

You don't need that. For example 170 degrees for a line is the same as -10 degrees. If it makes you feel better, just randomly add or subtract 180 from the angle.
