Embodiment Construction

[0065] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0066] figure 1 It is a flow chart of an occluded face recognition method shown in an exemplary embodiment, which is applied to electronic devices. Such as figure 1 As shown, the method may include the following steps.

[0067] In step 101, an image of a target occluded face is acquired. In the present disclosure, the target occluded face image refers to the face image under the occlusion condition to be recognized. An electronic device may acquire a target-occluded face image in various ways. For example, the target occluded face image may be acquired through a camera set on the electronic device, or the target occluded face image may be acquired from a...

Abstract

The invention relates to a shielding face identification method and a shielding face identification device. The method comprises steps that a target shielding face image is acquired; the target shielding face image is pre-processed to acquire the sample data of the target shielding face image, and the sample data is taken as the test sample data; an estimate of a first expression coefficient of the test sample data on a training sample set is determined; according to the training sample set, the test sample data and the estimate of the first expression coefficient, a shielding mask and a recovery mask are determined; the no-shielding estimation data of the test sample data is determined according to the estimate of the first expression coefficient, the shielding mask and the recovery mask; an estimate of a second expression coefficient of the no-shielding estimation data on the training sample set is determined; an identity identification model is constructed according to the training sample set and the estimate of the second expression coefficient; the no-shielding estimation data is inputted to the identity identification model, and the identity information of the target shielding face image is acquired. Through the method, a shielding face can be simply, efficiently and accurately identified.

Description

technical field [0001] The present disclosure relates to the field of face recognition, and in particular, to a method and device for occluded face recognition. Background technique [0002] Face recognition is an important part of the field of biometric recognition. It has certain advantages in terms of universality, uniqueness and easy collection. It has high academic research value and market application prospects. It has gradually developed into the current pattern recognition field. One of the most representative and challenging research contents. After years of research, face recognition technology has achieved fruitful research results, but these results were mainly obtained in a strictly restricted laboratory environment. With the application and popularization of digital cameras, smart phones and intelligent monitoring systems, face recognition in real life scenes and unconstrained environments has gradually become a research hotspot. [0003] In the public litera...
