Bath, England: Smart Sensors, spun out from the University of Bath, introduced version 2 of its MIRLIN software toolkit. Thus, security-system developers can create iris-recognition systems capable of 2 million matches/s. Functions include image acquisition, enrollment, and verification or determination of identity (ID) from human irises.
Analyzing a digital image of the iris using techniques similar to those employed in video encoding, the Smart Sensors patented solution requires less processing power than alternative methods. The software code is able to operate in just 300 kB of chip memory.
MIRLIN software development kits optimize systems for the best combination of speed and accuracy. Images can be scanned in segments from 18º to 0.72º wide, depending on the accuracy required.
