Intrigue Technologies, led by Vladimir Brajovic, has developed software that can "intelligently correct for common illumination problems in photography." The technology the firm is developing makes it possible to balance exposure across images, creating cleaner images and improving contrast. A news release posted on the website describes the product more generally. Also available from this site is an online demonstration of the company's software plug-in, the Shadow Illuminator, which includes a presentation of the images that have been adjusted using the software, a manual explaining how the software works, and a sample version of the product to download and try free of charge. The company's goal is to create an optical device that "will work more like a retina than a standard imaging sensor." Researchers anticipate that future developments will improve robots' visual-sensing, allow for piloting vehicles in extreme weather, and improve the reliability of machine-vision systems, such as those for biometric identification, X-ray diagnostics and space exploration imagers.
