Detailed Description

Gaze estimator interface.

Note: This estimator is designed to work with 68 facial landmarks, HeadPoseEstimation (

See Also: IHeadPoseEstimator) and EyesEstimations of both eyes (; IEyeEstimator).; GazeEstimation structure for details about how exactly the estimations are reported.

Note: Input points should be relative to the same coordinate system. Best results are achieved if coordinate system is tied to image on which input data was retrieved.

Member Function Documentation

virtual Result<FSDKError> fsdk::IGazeEstimator::estimate	(	const Image &	warp,
		const Landmarks5 &	landmarks5Transformed,
		GazeEstimation &	eyeAngles
	)		const

pure virtualnoexcept

Estimates the eye angles.

Parameters

[in]	warp	image with warped face. Format must be R8G8B8 or IR_X8X8X8.
[in]	landmarks5Transformed	transformed landmarks.
[out]	eyeAngles	output estimation;

virtual Result<FSDKError> fsdk::IGazeEstimator::estimate	(	Span< const Image >	warps,
		Span< const Landmarks5 >	landmarks5Transformed,
		Span< GazeEstimation >	eyeAngles
	)		const

pure virtualnoexcept

Estimates eye angles of multiple frames in a single estimate function call.

Parameters

[in]	warps	span of warped faces. Format must be R8G8B8 or IR_X8X8X8.
[in]	landmarks5Transformed	span of transformed landmarks of size 5.

Parameters

[out] eyeAngles output span of gaze estimations;

Note: all spans should be based on user owned continuous collections.; all spans should be equal size.

virtual fsdk::Point2i fsdk::IGazeEstimator::getFaceCenter ( const fsdk::Landmarks5 & landmarks5 ) const

pure virtualnoexcept

Returns the special center of face for calculating of gaze projection.

Parameters

[in] landmarks5 landmarks of size 5

virtual Result<FSDKError> fsdk::IGazeEstimator::validate	(	Span< const Image >	warps,
		Span< const Landmarks5 >	landmarks5Transformed,
		Span< Result< FSDKError >>	errors
	)		const

pure virtualnoexcept

Validate input of multiple frames in a single function call.

Parameters

[in]	images	warps span
[in]	landmarks5Transformed	span of transformed landmarks, only for Validation.
[out]	errors	output span of errors for each image.
