# FaceAnalyser.underExposureSensibility Property

Module: FaceAnalyser

Type: int

## Definition

Sensibility of the under-exposure classifier, from 0 to 255.

The higher the value, the more sensitive the algorithm will be, meaning that it will be more likely to estimate under-exposed face images.

Hint

Default value is 66.

Python

    under_exposure_sensibility: int

Exceptions

> FaceException
> An error has occurred during Face Library execution.

Dart

    int get underExposureSensibility => getUnderExposureSensibility();
    set underExposureSensibility(int value) => setUnderExposureSensibility(value);

Exceptions

> FaceException
> An error has occurred during Face Library execution.

C#

    public int underExposureSensibility
    {
        get => GetunderExposureSensibility();
        set => SetunderExposureSensibility(ref value);
    }

Exceptions

> FaceException
> An error has occurred during Face Library execution.

Java

    public int getUnderExposureSensibility() throws FaceException
    public void setUnderExposureSensibility(int underExposureSensibility) throws FaceException

Exceptions

> FaceException
> An error has occurred during Face Library execution.

Swift

    public var underExposureSensibility: Int
        get {
            return Int(try! getUnderExposureSensibility())
        }
    }

Exceptions

> FaceException
> An error has occurred during Face Library execution.

C

    int id3FaceAnalyser_GetUnderExposureSensibility (ID3_FACE_ANALYSER hFaceAnalyser, int * underExposureSensibility)
    int id3FaceAnalyser_SetUnderExposureSensibility (ID3_FACE_ANALYSER hFaceAnalyser, int underExposureSensibility)

Returns

> `int`
> An error code.
> See id3FaceError file for the list of possible error codes.
