Intel support agent Juan said on February 18 that "I have checked with engineering and they have confirmed that support for Windows Hello with the new D400 family will never be developed".
What Intel has done is to open the door for 3rd parties... If you listen carefully, what they are saying is that if you develop facisl recognition, they won't be competing with you. It is inconceivable to me that that facial recognition using the D400 series won't be developed.
Admittedly you have to do the analysis yourself, but there is a world full of experts available. This is raw data the only filtering was to put a virtual limit on the background... digital green screen.
There are lots of ways to clean up the noise and fill in the blanks:)
A face scanner will have to use 2 cameras... notice the occlusions caused by my cinematic nose:)
Thanks for sharing about CloudCompare!
Intel are encouraging third parties to develop solutions in partnership with them, and also welcome GitHub contributions from community members. An example of this is the community-contributed samples and guides in the Community Projects section of the SDK 2.0 samples web-page, and the Nuitrack skeletal tracking software.
