Detailed Description

Liveness flow estimator interface.

Note
This estimator is designed for liveness detection. It works with 1 close-range face crop and 10 long-range face crops estimating correctness of optical flow between theese frames.
Required input images - 96x96 face warp central crops.
See Also
IWarper for details.
