Abstract

The invention provides an expression recognition method and device and an expression recognition model training method and device, and the method comprises the steps: processing a to-be-recognized image, so as to obtain a face image; representing each pixel point in the face image by using a quaternion to form a face quaternion matrix, with the weight of each imaginary number in the quaternion representing the value of a corresponding color component; and taking the human face quaternary matrix as the input of a target neural network model, and recognizing the to-be-recognized image to obtainthe expression of the human face in the to-be-recognized image.

Description

technical field [0001] The present application relates to the field of image processing, in particular, to an expression recognition method, expression recognition model training method and device. Background technique [0002] Expressions are the most intuitive expression of people's inner feelings. Based on the development of neural networks, some existing technologies use neural network models to recognize expressions. However, the existing recognition methods still have some problems of low recognition accuracy. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present application is to provide an expression recognition method, an expression recognition model training method and a device. It can achieve the effect of improving the accuracy of facial expression recognition. [0004] In the first aspect, the embodiment of the present application provides an expression recognition method, including: [0005] Process the image to ...
