利用OpenCV实现在Android系统下的人脸检测

his paper proposes a method of human face detection based on OpenCV(Open Source Computer Vision) in Android system. It is briefly introduced how to build development environment and the implementation process of this application program using the Android framework. Implementation steps of using JNI (Java Native Interface) to call the relative functions of OpenCV are explained in detail and Specifies of using Android NDK (Native Development Kit) to generate shared library are mentioned. The experimental results show the human face detection of this Android application program has good performance.
