Embodiment approach

[0160] An optional implementation manner, the baseline determination module includes:

[0161] determining a horizontal centerline of said first interval;

[0162] If the facial expression index corresponding to the horizontal center line is greater than the first threshold and less than the second threshold, then the horizontal center line is determined to be the reference line corresponding to the human face in a natural state;

[0163] If the facial expression index corresponding to the horizontal center line is less than or equal to the first threshold, then the horizontal line corresponding to the first threshold is determined as the corresponding baseline of the human face in a natural state;

[0164] If the facial expression index corresponding to the horizontal center line is greater than or equal to the second threshold, the horizontal line corresponding to the second threshold is determined as the reference line corresponding to the human face in a natural state.

Abstract

The invention discloses a facial expression analysis method and system. The method comprises the steps: obtaining a to-be-analyzed facial expression video clip, and obtaining a picture stream in the video clip; analyzing the facial expression index of each frame of picture in the picture stream, and determining a facial expression spectrogram corresponding to the picture stream; according to the facial expression spectrogram, determining a reference line corresponding to the human face in a natural state, and determining a natural emotion area of the human face in the natural state based on the reference line; and dividing the face expression spectrogram into a plurality of emotion regions corresponding to different expressions by taking the natural emotion region as a reference. The invention also provides a facial expression satisfaction analysis method and system. According to the method, the complete video information of the expression of the user is utilized, the fluctuation of the expression is fully considered, the real emotion of the user can be determined, and the satisfaction degree of the user can be accurately determined.

Description

technical field [0001] The present invention relates to the technical field of data analysis, in particular to a method and system for analyzing human facial expressions and a method and system for analyzing satisfaction. Background technique [0002] In related technologies, when analyzing facial expressions, most of them just train neural network models based on training data and corresponding annotation information, input the object to be predicted into the trained neural network model, and obtain facial expression analysis results. However, facial expressions fluctuate, that is, the face does not remain happy, calm or angry every second, which makes the facial expression analysis results inaccurate. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a method and system for analyzing human facial expressions and a method and system for analyzing satisfaction, which utilizes the complete video inform...
