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.
