Very tiny bar codes

Multicolor 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...

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...

Bar 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....

Decoding bar codes from human-readable characters

In this study we have decoded bar codes by recognizing the human readable characters of the interpretation line printed below the bar pattern Using this approach we were able to successfully decode bar codes with a resolution of pixels per module
