For our January 2019 issue, we cover recent patents granted in the area of face recognition.
In one embodiment no. 10,162,999, a method includes accessing an image file associated with a first user of a communication system and detecting a face in an image corresponding to the image file. The method also includes accessing an event database associated with the communication system, the event database containing one or more events, each being associated with the first user and one or more second users of the communication system. The method also includes determining one or more candidates among the second users to be matched to the face, where each candidate is associated with an event in the communication system, and where a time associated with the image is in temporal proximity to a time associated with the event
Patent no. 10,146,797 presents methods, systems, and apparatus, including computer programs encoded on computer storage media, for storing facial recognition image data in a cache. One of the methods includes receiving an image from a camera, detecting, in the received image, a face of a person, searching a biometric data cache based on the detected face, in response to searching the biometric data cache based on the detected face, determining whether the biometric data cache includes data for the person, in response to a determination that the biometric data cache includes data for the person, using the data from the biometric data cache to determine an identifier for the person, and in response to a determination that the biometric data cache does not include data for the person: searching a data storage system based on the detected face of the person to determine whether the data storage system includes data for the person.
According to patent no. 10,108,851 a video conference invite is accessed and names and/or account addresses in the invite are used to obtain information of people listed on the invite from a database. The information can include template photographs of the people and locations of the people. During a video conference that is subject of the invite, when it is determined that a video feed of the video conference indicates that plural participants are together in a single room, images of faces in the video feed are efficiently matched against only template photographs of people in the database indicated by the database as being associated with the room.
Patent no. 10,102,421 presents a method for face recognition in the video comprises: performing feature extraction on a target face in multiple image frames in the video to generate multiple face feature vectors respectively corresponding to the target face in the multiple image frames; performing time sequence feature extraction on the plurality of face feature vectors to convert the plurality of face feature vectors into a feature vector of a predetermined dimension; and judging the feature vector of the predetermined dimension by using a classifier so as to recognize the target face.
The invention no. 10,061,996 comprises capturing an image of a subject to be authenticated; a step of face verification; followed by the process steps of a scan line detection test, a specular reflection detection test, and a chromatic moment and color diversity feature analysis test in no particular order. The method requires a subject to present her face before a camera, which can be the built-in or peripheral camera of e.g. a mobile communication device or a mobile computing device. The method also requires displaying to the subject certain instructions and the real-time video feedback of the subject face on a display screen, which can be the built-in or peripheral display screen of the mobile communication device or mobile computing device.
In patent no. 10,033,973 systems and methods for customizing a personalized user interface of an IP video door phone using face recognition are provided. Methods can include receiving an image of a user captured by a camera, performing face recognition processing on the image to identify an age of the user, identifying a customized user interface associated with the age of the user, and causing a display screen to display the customized user interface.
A system presented in patent no. 10,026,022 trains a facial recognition modeling system using an extremely large data set of facial images, by distributing a plurality of facial recognition models across a plurality of nodes within the facial recognition modeling system. The system optimizes a facial matching accuracy of the facial recognition modeling system by increasing a facial image set variance among the plurality of facial recognition models. The system selectively matches each facial image within the extremely large data set of facial images with at least one of the plurality of facial recognition models. The system reduces the time associated with training the facial recognition modeling system by load balancing the extremely large data set of facial images across the plurality of facial recognition models while improving the facial matching accuracy associated with each of the plurality of facial recognition models.
The disclosure no. 10,019,624 relates to a face recognition system. The face recognition system includes a camera module configured to acquire face recognition information of a target object; a feature point recognition module configured to select facial feature points; a displacement output module configured to output a displacement and azimuth of the camera module during acquiring the face recognition information at different positions; a distance calculation module configured to calculate depth distances between the facial feature points and the displacement between the different positions; and a face recognition module configured to judge whether the target object is the target user. A face recognition method is also related.
