基于可视色差与区域生长的彩色图像分割

提出了一种基于可视色差和分块区域生长的彩色图像分割算法,首先将待处理图像划分成若干大小相同的子块,在CIEL*a*b*颜色空间中计算每个子块的色彩均值和方差值,根据方差值对子块分类,利用可视色差对颜色均匀子块分类、合并,获得初始分割区域,利用四叉树算法对纹理子块分裂合并,然后从初始分割区域开始生长、合并,并删除小颜色块。实验结果证明了算法的有效性,分割结果符合人的主观感知。

A Color Image Segmentation method based on visible color difference and region growing

The article brought forward a color image segmentation algorithm based on visible color difference and sub-block region growing techniques.Firstly,the original image is first divide into sub-blocks which are not overlapped.In CIELab space,calculate the mean and variance of every sub-black,classify the sub-block with the variance of it,it achieve initial region by classifying and mergeing the color uniform sub-blocks with visible color-difference,split and merge the texture sub-block with quadtree,final grow...
