Computer Vision Experiment: Barcode Scanner

Posted on 2010-12-02 By rv6502 No Comments on Computer Vision Experiment: Barcode Scanner

UPC_decoder5Some more experimenting with a cheap low quality webcam for extra challenge (Moar with less!).

This time its a barcode scanner with no controlled light source.
I wanted to scan barcodes with just the ambient lighting so I had to design an image filter that would amplify the picture’s contrast and reconstruct the dark and light zones from a very low quality source.
I was then able feed the corrected image to a barcode decoding neural network.
