摘要
提出一种基于主元分析和色调的彩色图像分割方法.首先应用主元分析法确定分类数,将彩色图像分成几个区域,然后基于色调特征将区域再划分为若干个子区域,最后根据CIE(L*a,b*)空间的颜色差异合并具有相似颜色的子区域,得到最终的精确分割结果.
A new method of color image segmentation based on principal component analysis（PCA） and hue is presented. First color image is partioned into several areas according to classified number determined by PCA. Then these areas are segmented into divers sub-areas based on hue. Last sub-areas having similar colors are merged on grounds of color difference in CIE（L^＊ a^＊ b^＊ ） space to get accurate segmentation result Key words：
