摘要： A method for recognizing masked faces includes: obtaining a face image to be recognized; detecting whether the face image to be recognized has a mask; extracting feature vectors of a whole face in the face image to be recognized when the face image to be recognized does not have a mask; comparing the feature vectors of the whole face with face images in a first database, and outputting a face recognition result; extracting feature vectors of an upper half face in the face image to be recognized when the face image to be recognized has a mask; comparing the feature vectors of the upper half face with face images in a second database, and outputting the face recognition result. The method of the present disclosure processes images of faces with and without masks, expanding application scenario of face recognition and improving the accuracy of recognition.

摘要： A method for recognizing, identifying, and authenticating persons to be identified from their faces in a preset scenario, includes uploading a first image of users to a server, and receiving the first image on which first facial rectangles and user information have been imposed, and capturing a second image and detecting second facial rectangles therefrom. The method determines whether a number of faces of the second image is equal to a number of faces of the first image, and uploading the second image to the server for identifying third facial rectangles of the second image. A plurality of distances is obtained by calculating at least one distance between third and second facial rectangles of each user shown in the second image and determining whether the users shown in the second image are the same as users shown in the first image based on the plurality of distances.

摘要： A device and a method and a non-transitory readable storage medium, for face recognition are provided, the method comprise: extracting a face sample image from a predetermined face sample library and performing feature point detection to obtain multiple face feature points; obtaining multiple mask images; selecting first to fourth face feature points from the multiple face feature points; defining a distance between the first and second face feature point as a mask image height, and defining a distance between the third and fourth face feature point as a mask image width; adjusting a size of each mask image according to the mask image height and the mask image width; fusing each adjusted mask image with the face sample image to obtain multiple face mask images to save into the predetermined face sample library; training a face recognition model based on the predetermined face sample library for face recognition.

摘要： A face recognition method applied to establish authentic or artificial faces before searching for a person match in a database includes establishing a deep network model, obtaining training data and training the deep network model using the training data. An original image of a human face and a depth image corresponding to the original image are obtained, and authenticity or artificiality is determined by preset methods including use of cosine similarity algorithm. Matching an original image determined as authentic against face images pre-stored in an image database and outputting any match, when the original image is the image of a real person. A face recognition device is also provided.
