lsdk::IUnifiedLiveness Struct Referenceabstract
Liveness detection.

Unified liveness detector interface. This liveness type includes previous types and performs all calculation in one session. It performs tracking of value of type used on the creation stage, besides it also tracks remaining measurements in order to identify fraud attempt. More...

Detailed Description

Unified liveness detector interface. This liveness type includes previous types and performs all calculation in one session. It performs tracking of value of type used on the creation stage, besides it also tracks remaining measurements in order to identify fraud attempt.

Note
LA_INFRARED typ is not used.

Member Function Documentation

virtual void lsdk::IUnifiedLiveness::consider ( uint32_t  flags)
pure virtualnoexcept

Sets liveness types to take into consideration.

Parameters
flagsuint32_t bit field.
Note
bit value (1/0) enables/disables tracking, bit position corresponds to the type of liveness to consider according to scheme: |LA_COUNT|...|LA_EYEBROW|LA_MOUTH|...|LA_PITCH_UP|LA_PITCH_DOWN| | 9| | 6| | | 1| 0|
By default all types of tracking are enabled;
LA_COUNT bit enables all types of tracking;
LA_PITCH_UP, LA_PITCH_DOWN, LA_YAW_LEFT, LA_YAW_RIGHT enable face angles tracking;
Composition function is provided for convenience,
See Also
field() for more information.
virtual int lsdk::IUnifiedLiveness::getBlinkCounter ( )
pure virtualnoexcept

Gets blink stats.

Returns
number of registered blinks.
