## Detailed Description

OneShot RGB Liveness estimator interface.

Note
  This estimator is designed for liveness detection.

## Member Function Documentation

## ◆ estimate() [1/2]

virtual Result<FSDKError> fsdk::ILivenessOneShotRGBEstimator::estimate | ( | const Image & | image,
|  | const Detection & | detection,
|  | const Landmarks5 & | landmarks5,
|  | LivenessOneShotRGBEstimation & | estimation,
|  | float | qualityThreshold = `-1.f`
| ) |  | const
| pure virtual noexcept

OneShot RGB Liveness estimation.

Parameters

  [in] | image | source image.
  [in] | detection | detection coordinates in image space;
  [in] | landmarks5 | Landmarks5 for the detection;
  [out] | estimation | estimation results.
  [in] | qualityThreshold | quality threshold;

Returns
  Result with error code.

See also
  Detection, LivenessOneShotRGBEstimation, Landmarks, Image, Result and FSDKError for details.

Note
  image format must be R8G8B8,

  Format.

## ◆ estimate() [2/2]

virtual Result<FSDKError> fsdk::ILivenessOneShotRGBEstimator::estimate | ( | Span< const Image > | images,
|  | Span< const Detection > | detections,
|  | Span< const Landmarks5 > | landmarks5,
|  | Span< LivenessOneShotRGBEstimation > | estimations,
|  | float | qualityThreshold = `-1.f`,
|  | LivenessOneShotRGBEstimation * | aggregation = `nullptr`
| ) |  | const
| pure virtual noexcept

OneShot RGB Liveness estimation.

Parameters

  [in] | images | span of source images;
  [in] | detections | span of detection coordinates in corresponding source images space;
  [in] | landmarks5 | span of Landmarks5;
  [out] | estimations | span of estimations;
  [in] | qualityThreshold | quality threshold;
  [out] | aggregation | aggregated value based on estimations;

Returns
  Result with error code.

|  | Span< const Detection > | detections,
|  | Span< const Landmarks5 > | landmarks5,
|  | Span< Result< FSDKError >> | errors
| ) |  | const
| pure virtual noexcept

Validate input of multiple frames in a single function call.

Parameters

  [in] | images | span of source images.
  [in] | detections | span of detection coordinates in corresponding source images space.
  [in] | landmarks5 | span of landmarks
  [out] | errors | output span of errors for each image.

Returns
  Result with error code.

See also
  Span, Landmarks, Image, Result and FSDKError for details.
