Dear all,
I have an image that I need to draw points (can be cross or circles) over specified regions. But the total number of points would depend on the features identified in the image. In that regard, I would like to ask:
  1. It is possible to click over an image and draw points as I localize the intended features?
  2. Can I store the total of points selected?
Bets regards,
Leonardo

If you have the image processing toolbox, there are a few tools that do what you're describing.
drawpolygon() https://www.mathworks.com/help/images/ref/drawpolygon.html
drawpolyline() https://www.mathworks.com/help/images/ref/drawpolyline.html
and others like drawassisted | drawcircle | drawcrosshair | drawcuboid | drawellipse | drawfreehand | drawline
