Barcodes detected when none present

Post by rmajewski » Mon Sep 19, 2005 3:51 pm

I'm calling DetectBarCodePositions then GetBarCodePositionStructValues and then ReadSkewedCode39BarCode to read barcodes. It works great on images that have barcodes but I have a couple of images that are nothing more than text (a page of CONSTANT delcarations from a program listing) and DetectBarCodePositions is detecting multiple barcodes and ReadSkewedCode39BarCode is reading the phantom barcodes. How can I prevent this from happening?

I think I found the problem. I had the minimal side length ratio set to 5/10. I changed it to 25/10 and it appears to have fixed it.
