In one of the analysis methods we are developing, I need to determine the
location of a rectangular area that is made up of tiny dots in an image. In
print terms it is a 20% to 80% screen. The area beterrn the dots is white
the dots are black
Once I have the area identified, I can perform the analysis on the image.
Unfortunately right now finding the area to analyze takes as long as doing
the analysis.
Any thoughts on a technique that might be more efficient?
