The board supports Linux 4.14.98, and Android 9.0. NXP eIQ machine learning software is based on OpenCV and includes pre-optimized libraries and tools for computer vision applications. C++, Python, and Java API, and integration with MCUXpresso SDK and Yocto development environments aims to accelerate the development flow of the ML applications.
A facial recognition demo is included with the development kit. It relies on a Qt5 GUI, eIQ OpenCV ML software to compare the faces captured by the camera against registered face images in a database using the Django framework. The board also sends real-time data to the cloud via Ethernet and WiFi, so that authorized access and unauthorized detection can be visualized on a web dashboard.
One of the main use cases of the development kit is access control with face recognition solutions being much safer than fingerprint-based access control solutions in the time of COVID-19, as it enables zero-contact access application by using individuals’ faces to authorize access to a commercial/industrial space, home/office, transportation, banking, and government sites.
