Apple Wins a Patent for Future Face ID Features that use Machine Leaning to better Detect Partial Faces & those in Low Light

1 cover face ID with machine learning


The U.S. Patent and Trademark Office officially published a series of 73 newly granted patents for Apple Inc. today. In this particular report we cover Apple's future Face ID advancements so as to allow for partial face recognition and allowing Face ID to work better in challenging lighting conditions. All three of Apple's inventors are part of the company's Machine Learning team.


Currently Face ID processes typically reject an image for face detection (and downstream processes) if only part of a face is detected in the image. Such images are often rejected because the face detection is not reliable in detecting partial faces.


Apple's invention covers a neural network on a device that implements Face ID, which is a face detection process that captures an image using the TrueDepth camera on the device.


The face detection process may assess if a face is in the image and, if a face is detected, provide a bounding box for the face in the image. The advanced face detection process may provide face detection for any orientation of the face in the image (e.g., the face is detected regardless of the orientation of the face in the image).


Additionally, the face detection process may provide face detection for images that include either the user's entire face or only a portion of the user's face. The bounding box may also be located for an entire face or only the partial face present in the image.
