Iris-focused biometrics firm EyeLock has announced that the United States Patent and Trademark Office (USPTO) has issued patent that uses conditions of the iris to predict a time sequence for acquiring a high probability of quality iris images.The invention then acquires a series of images during that window.”Our latest patent – the company's 47th – contributes to the performance and strength of EyeLock's capabilities and intellectual property in the mobile space,” said Jim Demitrieus, CEO of EyeLock. “This patent complements EyeLock's recently issued U.S. Patent No. 9,626,563.”Demitrieus noted that this invention:uses conditions about the iris (iris area exposed to a camera, sharpness of features) to predict an upcoming time window during which there is a high probability that good images can be acquired for biometric purposes;performs opportunistic acquisition of a number of iris images during that time window, from which a limited number of images with higher quality scores are retained in memory for further processing;does not require autofocus functions that often trail user movements and fail to achieve good image focus;evaluates acquired images in real time to retain one or more images with better quality scores corresponding to the extent an imaged iris is exposed and in-focus;supports mobile or other applications where biometric acquisition may coincide with eye-blinking or is susceptible to motion blur due to user movements at instant of acquisition; andsupports mobile or other applications where the device memory available for retaining images is often limited.
