摘　　要：介绍结合人脸检测技术及相关图像处理技术实现在3G时代移动增值业务中的一个应用变脸。变脸首先采用Intel开源OpenCV人脸检测确定图像人脸的区域,然后采用独创的变异Snake算法提取人脸边缘轮廓,接着在YCbCr颜色空间对人脸肤色进行调整,使其肤色接近目标人脸肤色,最后基于数学形态学的模板边缘羽化对人脸轮廓结合处进行边缘羽化,很自然地把一张人脸替换成另一张人脸。Combining face detection technology to related image processing technology,application in the times of 3G mobile value - added service - changing face is implemented. Adopting Intel open - source OpenCV face detection to identify images of face region, then using original Snake algorithm to extract face edges and then adjusting the face in YCbCr color space to make it near the target color. Finally, the template based on mathematical morphology on the brink of eclosion face contour edge junction eclosion,it is natural to put a human face replaced by another face.
