Hi,
I have a diagram like these:
I would like to detect the region which is shaded.
Obviously, the shaded region is not really shaded, it just consists of a dense array of lines.
I am also makeing a line tracing algorithm to detect the real lines,
but these shaded lines distract my algorithm , so I need to remove them.
How do I detect the shaded regions and remove them?
Thanks a lot!
