This paper discusses the design of the expression recognition system in depth, especially the improvement of the feature extraction-related algorithm, in order to improve the accuracy of expression recognition and ultimately achieve the goal of the expression recognition system. This paper uses a method based on the improved AdaBoost algorithm and Haar features to improve the accuracy and speed of face detection.

After analyzing the theoretical imaging model of the camera and studying the nonlinear camera imaging model after introducing distortion parameters, the camera transformation matrix and the parameters in the camera are solved, and finally the calibration results are optimized. The experimental results show that the mean calibration error of this method is 0.1402 and the standard deviation is 0.0207, which has higher accuracy and better stability than the traditional calibration method and has certain engineering practical significance.","PeriodicalId":69487,"journal":{"name":"图像与信号处理","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66119472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
