Issue Description

Can D435 be used with face recognition applications? Is the depth data accurate enough to capture the features of a human face? If enough, what is the optimal setting of the best parameters for facial recognition。

Hi @pgswag Yes, the D435 camera model can be used with facial recognition to capture the landmarks of a human face. The RealSense SDK provides a couple of example projects.

C++ and Dlib - simple anti-spoofing application https://github.com/IntelRealSense/librealsense/blob/master/wrappers/dlib/face

C++ and OpenVINO https://github.com/IntelRealSense/librealsense/blob/master/wrappers/openvino/face

The default settings of the camera should be sufficient for facial recognition. If high confidence in the depth values is a requirement then the Medium Density camera configuration preset provides a good balance between accuracy and the amount of detail on the depth image.
