Adjusting brightness and contrast before using Emtion SDK?


#1

Hello

Does the brightness or contrast of the video matter, i.e. should it be adjusted before using the Emotion SDK so that the face is best visible?

Yes, moderate levels of brightness and contrast are best. The SDK provides some feedback on brightness in the Face::faceQuality metric:
