First capture, register/align and synchronize depth and RGB frames.
Second detect face land-marks in RGB frame
From the depth frame get the depth values exactly at land-marks detected in step 2
If you find uniform depth values or change in depth below a threshold, then it is flat surface -> fake/spoof face
