基于HIS色彩空间的水平集彩色图像分割算法

摘要

In order to solve the problem on how to quickly and effectively segment the color image,this paper puts forward the color image segmentation of rapid level sets based on HIS color space.First,this paper adopts the method of rapid level sets based on CV mode to improve the segmentation speed.Next,the segmentation of color image can be made with the introduction of the concept of color difference under HIS color mode.In this case,the segmentation can be made exactly even the grey color is very close or the same since the color information is fully employed.The experiment result shows this method mentioned here is more effective in color image segmentation than the traditional segmentation method of level sets.%针对如何能够有效快速地分割彩色图像的问题,本文提出了一种基于HIS色彩空间的快速水平集彩色图像分割算法.首先,为了提高分割速度,本文采用改进的CV模型的快速水平集方法进行图像演化.其次,针对彩色图像,本文采用在HIS色彩空间下引入彩色差概念进行分割.由于对色彩信息的充分利用,即使彩色图像灰度接近或相同时,仍能准确分割图像.实验结果表明,与传统水平集分割方法相比,本文的方法对彩色图像具有更好的分割效果.
