Hello,

I have barcode that I am creating via edge detect and imfill create the image below. Is there a way to convert the created rectangles into ones with nice sharp edges? I also wonder if its possible to correct the spacing. This is a Code-39 barcode so there is only small and large spacing that should be equivalent in size of the small and large bars present?

Thank you

Andrew

While you could do this, it will probably not be accurate enough to read as a barcode, you should try to clean up the image more before using edge detection.

If you still want to, I would locate the objects using bwpropfilt then use the positions as well as the major/minor axis to draw rectancles on a new blank image.
