# Are FaceFeatures in FeatureExtractor, grayscale or RGB images?

GROUPS:
 Nicola Cattabiani 1 Vote I am implementing a facial recognition system in the Wolfram Language, and I would like to know if the FeatureExtractor->FaceFeatures works best with grayscale or RGB images. I would like to know if the FeatureExtractor automatically converts RGB to grayscale or it preserve RGB colorspace to extract additional face features. ~ Thank You.
