Face recognition and liveness detection solution based on NXP EdgeReady MCU

NXP's EdgeReady MCU-based facial recognition solution leverages the i.MX RT106F crossover MCU to enable developers to quickly and easily add facial recognition with liveness detection capabilities to their products. Liveness detection prevents photo spoofing and is enabled by low-cost IR and RGB cameras. The solution’s development kit, SLN-VIZNLC-IOT, comes with fully integrated, turnkey software for rapid out-of-the-box operation, minimizing time to market, risk and development effort. Facial recognition is done entirely at the edge, solving many consumer privacy concerns. The NXP EdgeReady solution is part of the EdgeVerse™ edge computing platform.
