Super-resolution of bar codes
This paper 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...
متن کاملSuper-resolution of Defocus Blurred Images
Super-resolution is a process that combines information from some low-resolution images in order to produce an image with higher resolution. In most of the previous related work, the blurriness that is associated with low resolution images is assumed to be due to the integral effect of the acquisition device’s image sensor. However, in practice there are other sources of blurriness as well, inc...
متن کاملMulticolor chromosome bar codes.
Chromosome bar codes are multicolor banding patterns produced by fluorescence in situ hybridization (FISH) with differentially labeled and pooled sub-regional DNA probes. These molecular cytogenetic tools facilitate chromosome identification and the delineation of both inter- and intra-chromosomal rearrangements. We present an overview of the various conceptual approaches which can be largely d...
متن کاملThe Nonabelian Bar Resolution
We develop the theory of parity quasi-complexes (PQC), preparing the set up for defining derived functors using resolutions in the nonabelian case. A homotopy structure on the category of PQC is defined, yielding a 2-category structure. The nonabelian homology functor factors through the corresponding homotopy category. Following the relative homological algebra approach, resolutions are define...
متن کاملBar Codes Everywhere You Look
BAR CODE BASICS Labeling our world requires, well, labels. Today, this typically amounts to what’s commonly called a bar code. This term is synonymous with the Universal Product Code (UPC) and European Article Number (EAN) codes found on nearly every manufactured good and familiar to most consumers through their nearly ubiquitous use at grocery store checkouts. Depending on the exact type (www....
