Hi Greg, My use case is than I want to implement anti-spoofing system in which the app should be able to distinguish between real human face and a human face shown in a flat 2D smartphone screen or a printed photo. I have tried depthDataQuality it works when the subject is nearer to the camera when the spoof photo is displayed in a resolution screen and at some distance away from the true-depth camera the depthDataQuality becomes high.
