基于保边滤波的人脸美颜技术分析

Research on Face Beauty Technology Based on Edge Preserving Filter

随着科学技术的发展,相机和手机的拍照功能不断提高,拍摄的人像均为高清晰度的,但人脸部的斑、痘、皱纹等瑕疵同时会被清楚地记录下来。针对这一课题,本文提出了保边滤波的人脸美颜算法。首先分析了人脸美颜的原理,然后研究了保边滤波的两种方法,最后通过试验进行对比分析,得出清晰的美颜图像。经MATLAB2014a试验,该方法可以有效清除图像瑕疵噪点,明确图像的边缘化特征,基本可以实现对面部图像的美颜处理。

With the development of science and technology,the functions of cameras and mobile phones continue to improve.The portraits taken are all high-definition,but spots,acne,and wrinkles on the face are also clearly record ed at the same time.Aiming at this problem,this paper proposed a face-preserving algorithm based on edge-preserv ing filtering.Firstly,the principle of face beauty was analyzed,then two methods of edge-preserving filtering were re searched,and finally a comparative analysis was carried out through experiments to obtain a clear beauty image.Af ter MATLAB2014a test,this method can effectively remove image defects and noise,clarify the edge characteristics of the image,and basically achieve facial beauty treatment.
