| 摘 要： | 采用小波变换的方法对采集自同一被试的不同情感数据样本进行分析,从小波系数中提取心电图信号的情感特征.对同一天采集自同一被试的4种情感的特征进行比较分析,得出大小关系一致的特征作为情感识别依据.选取的特征在归一化之后对高兴和悲伤2类情感分类效果较好,最高可以达到92%.

| Abstract: | The key element of emotion recognition is to effectively extract emotion features from physiological signals.In this paper,a wavelet transform-based feature extraction is proposed to recognize emotions through ECG(electrocardiogram) signals.After the feature values of four emotion data that derived from one subject on the same day were compared and analyzed,the features that had uniform size relation were regarded as the evidence for emotion recognition.The normalized feature was used to recognize joy and s... |
