Hi Luis,

This question may have been asked before. I have a binary 2D image. I =
want to find the bounding box (min,max of x and y) of all ON pixels in =
the image. The only way I can think of is, Getting index of each on =
pixel using an iterator and finding min, max values on x and y. Is there =
already a function to do this?

Also, is there a function to find # of ON pixels in a binary image? Or =
do we have to again use an iterator to count ON pixels?
