Latest Patents

Zhijun He's latest patents include innovative systems for camera synchronization and image tagging for face authentication. This patent describes techniques for synchronizing cameras and tagging images to improve facial recognition accuracy. The system utilizes a dual infrared camera that alternates between capturing a 'flood image' and a 'dot image', tagging each with metadata to indicate its type. This approach addresses challenges such as dropped frames and errors in metadata tags, ultimately promoting more reliable facial recognition.

Another significant patent by Zhijun He involves automatic exposure and gain control for face authentication. This document outlines techniques that allow a user device to initialize a gain for a near-infrared camera system. By analyzing patch-mean statistics of regions-of-interest in recently captured images, the device computes an updated gain to achieve a target mean-luminance value. The system also incorporates hysteresis to dampen the updated gain, ensuring optimal performance in face authentication scenarios.
