Facial Emotion Recognition Using Nonparametric Weighted Feature Extraction and Fuzzy Classifier
نویسندگان
چکیده
The most facial emotion recognition methods use the geometrical features of face such as eye opening and mouth opening, which extraction of them is a hard and complicated task. But, in this paper, we propose to use the discriminant features simply extracted by nonparametric weighted feature extraction (NWFE). Moreover, to model the inherent uncertainties contained in the emotional features, we use the fuzzy measure in the classifier. To this end, a nearest neighbor classifier with fuzzy Euclidean distance is used to recognize emotions of face images. The experimental results on JAFFE database show the superiority of the proposed method compared to some other emotion recognition methods. Keywords— fuzzy; nearest neighbor; nonparametric weighted feature extraction; emotion recognition.

متن کاملFace recognition using nonparametric-weighted Fisherfaces
This study presents an appearance-based face recognition scheme called the nonparametric-weighted Fisherfaces (NW-Fisherfaces). Pixels in a facial image are considered as coordinates in a high-dimensional space and are transformed into a face subspace for analysis by using nonparametric-weighted feature extraction (NWFE). According to previous studies of hyperspectral image classification, NWFE...
