本文提出了一种新型的表情组合模板与Gabor小波相结合的面部表情识别方法.借助Gabor小波变换在图像处理领域的优势,克服不同因素给表情识别带来的不利影响,有效的提取与表情变化有关的特征,从分类的角度来构造的表情组合模板.在人脸检测的基础上,利用Gabor小波变换提取各个区域的特征矢量,与待识别表情对应的各个特征区域的特征矢量进行比较,利用欧氏距离选择最小值对应的矢量,返回表情组合模板中,确定待识别表情的类型.实验表明该方法的识别率可达83%,表情识别效果较好.
本文提齣瞭一種新型的錶情組閤模闆與Gabor小波相結閤的麵部錶情識彆方法.藉助Gabor小波變換在圖像處理領域的優勢,剋服不同因素給錶情識彆帶來的不利影響,有效的提取與錶情變化有關的特徵,從分類的角度來構造的錶情組閤模闆.在人臉檢測的基礎上,利用Gabor小波變換提取各箇區域的特徵矢量,與待識彆錶情對應的各箇特徵區域的特徵矢量進行比較,利用歐氏距離選擇最小值對應的矢量,返迴錶情組閤模闆中,確定待識彆錶情的類型.實驗錶明該方法的識彆率可達83%,錶情識彆效果較好.

This paper presents a new method of face recognition, with a combination of facial expression templates and Gabor wavelet. With the aid of Gabor wavelet transformation in the field of image processing, the method discussed could effectively extract charac-teristics of facial expression, overcome the negative impacts of individual differences as well as construct expression templates from the perspective of the classification. First, on the basis of face detection, we use of Gabor wavelet transformation to extract vector in each area. Then compares feature vectors of expression to be recognized in each feature area. After choosing the vector corresponding to the minimum by using Euclidean distance, it will turn back to the expression combination template and finally identify the type of expression. Experiments show that the identification rate of method is as high as 83% and the effect of expression identification is ex-cellent.
