## Member Function Documentation

## ◆ estimate() [1/3]

virtual Result<FSDKError> fsdk::IBlackWhiteEstimator::estimate | ( | const Image & | image,
|  | bool & | outIsGrayscale
| ) |  | const
| pure virtual noexcept

Check if image is grayscale or color.

Parameters

  [in] | image | source image.
  [out] | outIsGrayscale | estimation result; true if image is grayscale, false if not.

Returns
  Result with error code.

See also
  Image, Result and FSDKError for details.

Note
  image format must be R8G8B8,

See also
  Format.

## ◆ estimate() [2/3]

virtual Result<FSDKError> fsdk::IBlackWhiteEstimator::estimate | ( | const Image & | warp,
|  | ImageColorEstimation & | estimation
| ) |  | const
| pure virtual noexcept

Estimates if image is color, grayscale or infrared.

Parameters

  [in] | warp | image with warped face.
  [out] | estimation | estimation.

Returns
  Result with error code.

See also
  ImageColorEstimation, Image, Result and FSDKError for details.

Note
  warp format must be R8G8B8 or R8,

See also
  Format.

## ◆ estimate() [3/3]

virtual Result<FSDKError> fsdk::IBlackWhiteEstimator::estimate | ( | Span< const Image > | warps,
|  | Span< ImageColorEstimation > | estimations
| ) |  | const
| pure virtual noexcept

Estimates if images are color, grayscale or infrared.

Parameters

  [in] | warps | span of images with warped faces.
  [out] | estimations | array of estimations.

Returns
  Result with error code.

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

Note
  warps format must be R8G8B8 or R8,

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::IBlackWhiteEstimator::validate | ( | Span< const Image > | warps,
|  | Span< Result< FSDKError >> | errors
| ) |  | const
| pure virtual noexcept

Validates input of multiple frames in a single function call.

Parameters

  [in] | warps | span of images with warped faces.
  [out] | errors | output span of errors for each image.

Returns
  Result with error code.

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

Note
  warps format must be R8G8B8 or R8,

See also
  Format.

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