Hello everyone.
The Mixed Reality Forums here are no longer being used or maintained.
There are a few other places we would like to direct you to for support, both from Microsoft and from the community.
The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.
For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality.
If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.
And always feel free to hit us up on Twitter @MxdRealityDev.

Image recognition and 3D overlay

Is it possible to recognise features from the camera image such as holes in a surface or edges of the surface and compare with a 3D database of this surface to determine the users location and direction of view. Having determined the viewing location then augment 3D computer generated geometry with the camera image.

Anything is possible
@djb not as part of the Windows Holographic API, but this sort of functionality can be integrated with libraries like OpenCV. Here's great example of object recognition by the incredible artist/hacker Kyle McDonald with a different library. He even discusses how he put it all together. It should be a great starting point for you.

Related question: is there a recommendation for in-room registration / calibration to go with hololens (other than openCV and/or something along the lines of Project Oxford)?
@holothusiast You may find the Holograms 230 course from the Holographic Academy to be useful. It performs an initial room scan to ensure that the space is suitable (ex: has at least one wall and the floor has been located) for the example experience.

Please note that this course uses cached spatial mapping data (a snapshot of the user's environment) rather than a continuous scan. For benefits and drawbacks of each approach, see https://dev.windows.com/en-us/holographic/room_scan_ux#Cached_versus_Continuous_Spatial_Mapping.
Thanks!
