基于MATLAB的人脸图像分割算法研究

Research on facial image segmentation algorithm based on MATLAB

对基于MATLAB的人脸图像分割算法进行研究,利用颜色空间的不同色度特性,将给定的人脸图像按照不同色度划定的取值范围进行人脸和背景的分割。给出了三种颜色空间的基本原理,包括RGB颜色空间,HSV颜色空间,YCrCb颜色空间,对RGB颜色空间转换到HSV颜色空间和YCrCb颜色空间进行描述,并采用MATLAB软件完成图像的颜色空间转换。基于两种颜色空间完成不同类型人脸图像的图像分割,并对分割效果进行对比分析。

This article studies a facial image segmentation algorithm based on MATLAB,which utilizes the different chroma-ticity characteristics of color space to segment the given facial image from the background according to the range of values defined by different chromaticity.The basic principles of three color spaces are presented,including RGB color space,HSV color space,and YCrCb color space.It describes the conversion of RGB color space to HSV color space and YCrCb color space,and uses MATLAB software to complete the color space conversion of images.Complete image segmentation of different types of facial im-ages based on two color spaces,and compare and analyze the segmentation results.
