## Detailed Description

Face detection result batch interface.

## Member Function Documentation

## ◆ getDetections()

virtual Span< const Detection > fsdk::IFaceDetectionBatch::getDetections | ( | size_t | index = 0 | ) | const
| pure virtual noexcept

Returns detection Span.

Parameters

  [in] | index | index of the detection.

Returns
  span of detection coordinates in corresponding source images space.

See also
  Span and Detection for details.

Note
  all spans should be based on user owned continuous collections.
  Result Span could be empty in two cases:
  1. If no any faces were detected on the target image.
  2. If detection request didn't contain the DT_BOX flag.

  DetectionType

## ◆ getFace()

virtual Face fsdk::IFaceDetectionBatch::getFace | ( | const Image & | img,
|  | size_t | imageIndex,
|  | size_t | detectionIndex ) const
| pure virtual noexcept

Returns detected face.

Parameters

  [in] | img | source image.
  [in] | imageIndex | index of the image.
  [in] | detectionIndex | index of the detection.

Returns
  Detected face.

See also
  Face and Image for details.

Note
  images format must be R8G8B8,

See also
  Format.

Note
  Result Face could be invalid if no any faces were detected on the target image or parameters are invalid.

## ◆ getLandmarks5()

virtual Span< const Landmarks5 > fsdk::IFaceDetectionBatch::getLandmarks5 | ( | size_t | index = 0 | ) | const
| pure virtual noexcept

Returns Landmarks5 Span.

Parameters

  [in] | index | index of the landmarks object.

Returns
  Span of Landmarks5.

See also
  Span and Landmarks5 for details.

Note
  all spans should be based on user owned continuous collections.
  Result Span could be empty in two cases:
  1. If no any faces were detected on the target image.
  2. If detection request didn't contain the DT_LANDMARKS5 flag.

See also
  DetectionType

## ◆ getLandmarks68()

virtual Span< const Landmarks68 > fsdk::IFaceDetectionBatch::getLandmarks68 | ( | size_t | index = 0 | ) | const
| pure virtual noexcept

Returns Landmarks68 Span.

Parameters

  [in] | index | index of the landmarks object.

Returns
  Span of Landmarks68.

See also
  Span and Landmarks68 for details.

Note
  all spans should be based on user owned continuous collections.
  Result Span could be empty in two cases:
  1. If no any faces were detected on the target image.
  2. If detection request didn't contain the DT_LANDMARKS68 flag.

## ◆ getSize() [1/2]

virtual size_t fsdk::IFaceDetectionBatch::getSize | ( |  | ) | const
| pure virtual noexcept

Returns size.

Returns
  size of the detections.

## ◆ getSize() [2/2]

virtual size_t fsdk::IFaceDetectionBatch::getSize | ( | size_t | imageIndex | ) | const
| pure virtual noexcept

Returns size of the results for the target index.

Parameters

  [in] | imageIndex | index of the image.

Returns
  size of the results for the target index.
