How to Draw Crosshairs/Marked Axes
Is there some OpenCV routine that will draw crosshairs and/or mark the axes of an image in a Mat with tick marks? I have looked a bit and see no mention of one but it seems like something that a lot people probably do/want?
If there is no routine, any sample code would be appreciated. Also, is it faster to draw that for each image or make a template image and use that as a mask?
Thanks!
