Example Embodiment

[0058] The specific embodiments of the present disclosure will be described in detail below with reference to 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 used to limit the present disclosure.

[0059] figure 1 It is a flowchart of a method for recognizing a occluded face shown in an exemplary embodiment, which is applied to an electronic device. Such as figure 1 As shown, the method can include the following steps.

[0060] In step 101, an image of a face occluded by a target is acquired. In the present disclosure, the target occlusion face image refers to the face image under the occlusion condition to be recognized. The electronic device can obtain the target occluded face image in various ways. For example, a camera set on an electronic device can be used to obtain an image of a target occluded face, or an image of a target occluded face can be obtai...

Abstract

The present invention relates to a shielded face identification method and device. The method comprises: obtaining a target shielded face image; performing preprocessing of the target shielded face image, obtaining the sample data of the target shielded face image, and taking the sample data as the test sample data; determining the estimated value of the first expression coefficient of the test sample data on a training sample set; determining a shielding mark according to the training sample set, the test sample data and the estimated value of the first expression coefficient; determining the estimated value of the second expression coefficient of the test sample data on the training sample set according to the shielding mask; constructing an identity identification model according to the training sample set, the shielding mask and the estimated value of the second expression coefficient; and inputting the test sample data to the identity identification model, and obtaining the identity information of a figure expressed by the target shielded face image. The shielded face identification method and device can simply, efficiently and accurately identify the shielded face.

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...
