摘要
为了解决声音和图像情感识别的不足,提出一种新的情感识别方式:触觉情感识别。对CoST(corpus of social touch)数据集进行了一系列触觉情感识别研究,对CoST数据集进行数据预处理,提出一些关于触觉情感识别的特征。利用极限学习机分类器探究不同手势下的情感识别,对14种手势下的3种情感(温柔、正常、暴躁)进行识别,准确度较高,且识别速度快识别时间短。结果表明,手势的不同会影响情感识别的准确率,其中手势"stroke"的识别效果在不同分类器下的分类精度均为最高,且有较好的分类精度,达到72.07%;极限学习机作为触觉情感识别的分类器,具有较好的分类效果,识别速度快;有的手势本身对应着某种情感,从而影响分类结果。
To overcome the deficiencies of sound and image emotion recognition,a new emotion recognition method,haptic emotion recognition,is proposed.A series of haptic emotion recognition studies on Corpus of Social Touch(CoST) datasets were performed.First,the CoST data was preprocessed,presenting some features about haptic emotion recognition.Using the extreme learning machine classifier to explore emotion recognition under different gestures,three kinds of emotions,gentle,normal,and irritable,under 14 kinds of gestures,were identified with higher accuracy and a faster recognition speed(0.04 s).The results showed that differences in gestures will affect the accuracy of emotion recognition,wherein the recognition effect of the gesture "stroke" is the highest in classification accuracy under different classifiers.This new method yielded better classification accuracy,reaching 72.07%.As a classifier of haptic emotion recognition,the extreme learning machine had better classification effect and faster recognition speed.Some gestures corresponded to certain emotions,which affected the classification results.
