我们描述了一种新的人脸检测算法的基础上的层次结构的支持向量分类器(SVMs)。一些预处理步骤减少了候选人的数量,这应该由支持向量机进行验证。分层支持向量机是为从粗到精的人脸搜索而设计的。在SVMS中,眼睛分类器具有不同的复杂性(衡量的支持向量的数量)被用来找到眼睛的候选人。高效计算的收益是巨大的。该人脸检测系统还可以用于检测复杂背景下的多个人脸。此外,这种方法可以应用于不同种类的图像变化,如面部大小,照明条件和图像质量。
We describe a new face detection algorithm based on a hierarchy of support vector classifiers (SVMs). Some preprocessing steps reduce the number of candidates, which should be verifying by SVMs. Hierarchical SVMs are designed for coarse-to-fine search of human face. In the SVMS, eye classifiers with different complexity (measured by the number of support vector) are used to find the eye candidates. The gain for efficient computation is enormous. The proposed face detection system can also be used to detect multiple faces embedded in complicated background. In addition, this approach can be applied to different kinds of image variations such as face sizes, lighting conditions, and image qualities.
