Super-resolution of bar codes

  title={Super-resolution of bar codes},
  author={Donald G. Bailey},
  journal={J. Electronic Imaging},
This article describes how under-resolved images of bar codes may be read by suitable processing. A two-dimensional image of a bar code with insufficient resolution to be able to resolve the individual bars is processed to give a high-resolution image. For this to work, the bar code (or camera) must be slightly rotated to give a fraction of a pixel offset between rows. Since the bars are straight, the offset relative to the first complete row of the bar code increases linearly with vertical… CONTINUE READING
