Detailed Description

RGBM Liveness estimator interface.

Note
This estimator is designed for liveness detection.

Member Function Documentation

virtual Result<FSDKError> fsdk::ILivenessRGBMEstimator::estimate ( const Image image,
const Detection detection,
const Image background,
LivenessRGBMEstimation estimation 
) const
pure virtualnoexcept

Check if detection corresponds to person alive or not.

Parameters
[in]imagesource image.
[in]detectiondetection coordinates in image space.
[in]backgroundbackground for the track.
[in/out]estimation estimation structure
Returns
Result with error code.
See Also
LivenessRGBMEstimation, Detection, Image, Result and FSDKError for details.
Note
images format must be R8G8B8,
See Also
Format.
virtual Result<FSDKError> fsdk::ILivenessRGBMEstimator::update ( const Image image,
uint32_t  iFrame,
Image background 
) const
pure virtualnoexcept

Prepare background method. Pass here every frame from the stream to extract background.

Parameters
[in]imagesource image.
[in]iFramecurrent frame number.
[in/out]background current background. It will be updated by this call. Memory residence (host/gpu) of background image can be changed becase of internal implementation.
Returns
Result with error code.
See Also
Image, Result and FSDKError for details.
