Abstract

The invention discloses a privacy-protected facial expression recognition method and system, wherein the method includes the following steps: acquiring multiple color face images, and preprocessing the multiple color face images to obtain multiple color face images The color component; the color component is used as the imaginary part of the quaternion matrix, the first quaternion matrix is ​​constructed, and the local variance of the first quaternion matrix is ​​calculated; the local variance is used as the real part of the quaternion matrix, and the color component is used as The imaginary part of the quaternion matrix is ​​used to construct the second quaternion matrix; the quaternion Gyrator transformation is used to encrypt the second quaternion matrix to generate a real number matrix; the real number matrix is ​​randomly scrambled to train the convolutional neural network , and use the trained convolutional neural network to verify the color face image recognition. This method has stronger authentication performance, higher security and reversibility.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a privacy-protected facial expression recognition method and system. Background technique [0002] In daily life, facial images contain rich information, which not only conveys emotions but also conveys rich emotional information of communicators. With the continuous development of artificial intelligence, the research on facial expression recognition technology has become increasingly active, and it has been widely used in human-computer interaction, computer-aided learning, health monitoring and other fields. [0003] As an important biological characteristic, facial expression has certain privacy. The existing facial expression recognition algorithms do not fully consider the security of facial image information. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. ...
