## Detailed Description

BestShotQuality estimator interface.

Note
  This estimator is designed to work with Image and detection;

## Member Enumeration Documentation

## ◆ EstimationRequest

enum fsdk::IBestShotQualityEstimator::EstimationRequest

EstimationRequest lists all possible estimation attributes that BestShotQuality estimator is able to estimate.

Enumerator
estimateAGS | Estimate AGS.
estimateHeadPose | Estimate HeadPose.
estimateAll | Make full estimation (all attributes)

## Member Function Documentation

## ◆ estimate() [1/2]

virtual Result<FSDKError> fsdk::IBestShotQualityEstimator::estimate | ( | const Image & | image,
|  | const Detection & | detection,
|  | const EstimationRequest | request,
|  | EstimationResult & | result
| ) |  | const
| pure virtual noexcept

Estimate unified AGS and HeadPose attributes.

Parameters

  [in] | image | source image;
  [in] | detection | detection coordinates in image space;
  [in] | request | EstimationRequest structure;
  [out] | result | output estimation.

Returns
  Result with error code.
