Problem for contour extraction.

[DylanFan]

Hey,

I am wondering how can I extract ALL image contour by labview. My job is to extract all contour of image(suppose to be shown in green color), however the labview only gives me the contour in red which is even hard to find.

Thanks in advance!

Best Regards,

Dylan

Try edge therhold of 1.  What are you trying to accomplish here?  I think that if you need the contour of the individual letters, you will need much higher resolution.
