Bar Code Standardization by Creating New Symbology

Original scientific paper This paper proposes a new symbology which eases the use of any two-dimensional matrix bar code on the market from a user perspective, respecting the rules of each 2D matrix bar code. By proposing a new symbology, the exisiting function patterns are transfered into a digital space and additional parts are added. By adding a part called the rim, any 2D matrix bar code ca...

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...

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...
