Scientists have developed an image scanning program that can distinguish between individual zebras by their stripes:
When a zebra has been entered into the database and given a StripeCode, the researchers match another picture of the same animal by comparing the StripeStrings of the new and original images. Each image will generate a different set of StripeStrings, but the underlying ratios of black and white should remain similar.
By finding the StripeCode with the most similar StripeStrings in the database, the system is able to accurately identify the correct animal. Other existing zebra identification systems are less accurate, more complex, and require a greater level of manual input from the user.

The Japanese graphic arts firm d-barcode creates customized barcodes for clients who want to use them to grab customers’ attention. In Fast Company, Cliff Kuang writes:
They’ve even begun selling their wares to anyone who wants to license them, starting at $1,500 for the design, and $200 a year for licensing. A custom or exclusive use code will run upwards of $4,000–but given that companies spend millions on designing a single package, why don’t we see more detailed thinking like this? Middle managers spend weeks arguing about kerning–it’d be better if they spent more time rethinking every inch of such highly prized real estate.

Google’s doodle for today is a barcode, in honor of the 57th anniversary of its invention. Nick Collins writes in The Daily Telegraph about the history of this label:
Granted to American inventors Norman Joseph Woodland and Bernard Silver three years after it was filed, patent number 2,612,994 was for a pattern of concentric circles, rather than the set of straight lines used today.
Their research began in 1948 after Mr Silver, a graduate student at the Drexel Institute of Technology in Philadelphia, overheard a local food chain boss asking one of the institute’s deans to design a system for reading product data automatically.
Mr Silver and Mr Woodland, a fellow graduate student and teacher at Drexel, first tried using patterns of ink that glowed under ultraviolet light, but it proved too expensive and unreliable.
Mr Woodland then came up with the linear bar code, and later replaced the lines with circles so that they could be scanned from any angle. The pair patented their “bull’s eye” design the next year.
The barcode became widely used in UPC (universal price product code) format, and the first UPC-labeled item scanned by a reader was a packet of Wrigley’s chewing gum at a grocery store in Troy, Ohio in 1974.
