Techniques for detecting a three-dimensional face in facial recognition

A computer-implemented method for detecting three-dimensional features in validating a face for facial recognition, comprising:

• processing a first image captured by a first camera at a first time to determine a first set of multiple key points of a face in the first image;
• processing a second image captured by a second camera at a second time, that is equal to or within a threshold time of the first time, to determine a second set of the multiple key points on the face in the second image;
• determining, based on a first location of each of a portion of the multiple key points in the first image and a second location of each of the portion of the multiple key points in the second image, a three-dimensional location of at least the portion of the multiple key points in a three-dimensional space;
• and
• detecting whether the face is a valid three-dimensional face for facial recognition at least in part by comparing the three-dimensional location of at least the portion of the multiple key points to three-dimensional locations of similar key points of a classifier.

A non-transitory computer-readable medium, comprising code executable by one or more processors for detecting three-dimensional features in validating a face for facial recognition, the code comprising code for:

• processing a first image captured by a first camera at a first time to determine a first set of multiple key points of a face in the first image;
• processing a second image captured by a second camera at a second time, that is equal to or within a threshold time of the first time, to determine a second set of the multiple key points on the face in the second image;
• determining, based on a first location of each of a portion of the multiple key points in the first image and a second location of each of the portion of the multiple key points in the second image, a three-dimensional location of at least the portion of the multiple key points in a three-dimensional space;
• and
• detecting whether the face is a valid three-dimensional face for facial recognition at least in part by comparing the three-dimensional location of at least the portion of the multiple key points to three-dimensional locations of similar key points of a classifier.
