## Detailed Description

Eye estimator interface.

Note
  This estimator is designed to work with a person face image; you should pass a warped face detection image.

See also
  IWarper for details. Eye estimator detects:
  - eyes state;
  - landmarks describing iris.
  EyesEstimation for output details

## Member Function Documentation

## ◆ estimate() [1/2]

virtual Result<FSDKError> fsdk::IEyeEstimator::estimate | ( | const Image & | warp,
|  | const EyeCropper::EyesRects & | eyeRects,
|  | EyesEstimation & | eyesEstimation
| ) |  | const
| pure virtual noexcept

Estimate the attributes.

Parameters

  [in] | warp | image with warped face.
  [in] | eyeRects | EyeCropper::EyesRects structure with valid rectangle coordinates of each eye.
  [out] | eyesEstimation | Estimation of both eyes. Iris and Eyelid output landmarks are in warpedImage coordinates. If you want them in source of warpedImage image coordinates, use IWarper::unwarp

See also
  IWarper::unwarp.

Returns
  Result with error code.

See also
  EyesEstimation, EyeCropper::EyesRects, Image, Result and FSDKError for details.

Note
  warp format must be R8G8B8,

See also
  Format.

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

## ◆ estimate() [2/2]

virtual Result<FSDKError> fsdk::IEyeEstimator::estimate | ( | Span< const Image > | warps,
|  | Span< const EyeCropper::EyesRects > | eyeRects,
|  | Span< EyesEstimation > | eyesEstimations
| ) |  | const
| pure virtual noexcept

Estimate the attributes of multiple warped images in a single estimate function call.

Parameters

  [in] | warps | span of images with warped faces.
  [in] | eyeRects | span of EyesRects structure of corresponding warped image with valid rectangle coordinates of each eye.
  [out] | eyesEstimations | span of EyesEstimation of corresponding warped images. Iris and Eyelid output landmarks are in warpedImage coordinates. If you want them in source of warpedImage image coordinates, use IWarper::unwarp

See also
  IWarper::unwarp.

Returns
  Result with error code.

See also
  Span, EyesEstimation, EyeCropper::EyesRects, Image, Result and FSDKError for details.

Note
  warps format must be R8G8B8,

See also
  Format.

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

## ◆ validate()

virtual Result<FSDKError> fsdk::IEyeEstimator::validate | ( | Span< const Image > | warps,
|  | Span< const EyeCropper::EyesRects > | eyeRects,
|  | Span< Result< FSDKError >> | errors
| ) |  | const
| pure virtual noexcept

Validate input of multiple frames in a single function call.

Parameters

  [in] | warps | span of images with warped faces.
  [in] | eyeRects | span of EyesRects structure of corresponding warped image with valid rectangle coordinates of each eye.
  [out] | errors | output span of errors for each image.

Returns
  Result with error code.

See also
  Span, EyeCropper::EyesRects, Image, Result and FSDKError for details.

Note
  warps format must be R8G8B8,

  Format.

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