There is a tendency to quote large numbers to impress these days. If it is dollars then it’s trillions, if it’s data then it is Exabytes or even Zettabytes and if it’s CPU cycles it’s usually MIPs. This week, video recognition specialist idenTV said it passed 50 trillion image comparisons an hour and talks once more of sorting through Zettabytes of data. What idenTV does comes under Automated Content Recognition (ACR) but it augments this in a number of ways, claiming it uses Artificial Intelligence. It uses video fingerprinting and compares it with a database of cloud based image and video searches, but uses proprietary algorithms to do this exceptionally fast. It takes just a few seconds to check if…
