Abstract

The invention provides a customer satisfaction analysis method based on video face expressions. The method comprises the following steps of acquiring customer video data; using an expression method with a base portion to modeling a face shape and an appearance; distinguishing fitting, updating incremental expressions, and carrying out parallel fitting and fitting evaluation; and according to a fitting evaluation result, analyzing customer satisfaction. In the invention, a sample scope is wide, a customer does not need to subjectively evaluate and grade so that man-made subjective factors are eliminated and the data is objective; and simultaneously, a lot of questionnaire data is avoided and manual labor is reduced, and efficiency and accuracy are increased.

Description

technical field [0001] The invention relates to the field of video facial expression analysis, in particular to a method for analyzing customer satisfaction based on video facial expression. Background technique [0002] Traditional customer satisfaction surveys are carried out in the form of customer oral feedback and questionnaires. This kind of investigation consumes a lot of manpower, material and financial resources, the efficiency and accuracy are not high, and the data also contains human subjective factors. [0003] The present invention proposes a method for analyzing customer satisfaction based on video facial expressions. First, the video data of the customer's facial expressions is obtained by calling the video information in the camera of the service site such as a bank, a toll station, etc., and the facial expression image is used to The data set is trained; according to the facial expression changes in the video, the part-based representation method is used t...
