A Symbol-based Bar Code Decoding Algorithm

We investigate the problem of decoding bar codes from a signal measured with a hand-held laser-based scanner. Rather than formulating the inverse problem as one of binary image reconstruction, we instead determine the unknown code from the signal. Our approach has the benefit of incorporating the symbology of the bar code, which reduces the degrees of freedom in the problem. We develop a sparse...

Bar Code Waveform Recognition Using Peak Locations

adi it ion ally, zero crossings of the second derivative provide edge features for the classification of blurred waveforms. The accuracy of these edge features deteriorates in the case of severely blurred images. In this paper, a new feature is presented that is more resistant to the blurring process, the image, and waveform peaks. In addition, an estimate of the standard deviation of the blurr...

1D Bar Code Reading on Camera Phones

The availability of camera phones provides people with a mobile platform for decoding bar codes, whereas conventional scanners lack mobility. However, using a normal camera phone in such applications is challenging due to the out-of-focus problem. In this paper, we present the research effort on the bar code reading algorithms using a VGA camera phone, NOKIA 7650. EAN-13, a widely used 1D bar c...
