The present invention is applicable to the technical field of facial expression recognition, and provides a method and device for recognizing facial expressions, including: acquiring an image to be processed; extracting a human face image from the image to be processed; performing deep learning on the human face image Expression classification, obtaining the facial expression label of the human face image, wherein the human facial expression label indicates the expression of the human face; performing face verification on the human face image, obtaining the face verification result, wherein, The face verification result indicates information of the user to which the face belongs; and the face expression label and the face verification result are displayed. The present invention can solve the problems in the prior art that the accuracy rate of facial expression recognition is low, and the facial expressions lack correlation, and it is impossible to know different facial expressions of the same user.
Description
technical field [0001] The invention belongs to the technical field of facial expression recognition, and in particular relates to a method and a device for recognizing facial expressions. Background technique [0002] Facial expression recognition refers to analyzing and detecting the facial expression state from a given image, so as to determine the psychological emotion of the recognized object, such as naturalness, happiness, anger, surprise, etc. Facial expression recognition is an important field, which contributes to the development of many fields such as character mood analysis, character analysis, and depression detection. Therefore, it is of great value to solve the facial expression recognition human body. However, the existing facial expression recognition is not robust to expression features, and is easily disturbed by noise such as identity information, resulting in a low accuracy rate of expression recognition. At the same time, the current facial expression...
