| 摘 要： | 提出了一种基于肤色信息与改进的局部二值模式(LBP)算法的人脸检测方法。首先,用一种新颖的光照补偿方法对彩色图片进行光照补偿并分割肤色像素;其次,用正面人脸滤波窗口提取可能的人脸区域并用改进的LBP算子得到其纹理特征;最后,通过马氏距离比较可能人脸区域的LBP直方图与人脸/非人脸样本的LBP直方图的相似度,进行人脸的确认与定位。通过对caltechface database数据库、Labeled Facesinthe Wildatabase数据库、生活、网络和影视照片的实验验证,提出的方法是健壮与有效的。

| Abstract: | A method of face detection is proposed,which is based on the skin information and improved local binary pattern(LBP).Firstly,the color of the input picture is compensated by using a novel illumination compensation method and the skin pixels are segmented.Secondly,the possible face areas are extracted by frontal face filter windows and the LBP features of them are obtained by an improved LBP operator.Lastly,the Mahalanobis distance is used to verify and locate the face by comparing the LBP histograms of poss... |
