图像分割是进行图像理解与分析的基础,是图像工程技术中的一个重要问题, 也是图像处理的经典难题。彩色图像比灰度图像具有 更多的视觉信息, 因而受到了越来越多的重视。文章将彩色图像的分割技术分为三大类,并分别加以系统概括, 分析了各种方法的优缺点。(Image segmentation is the image understanding and analysis of the basis of the image engineering technology is an important issue, but also the classical image processing problems. Color image than the gray image with more visual information, which are more and more attention. Article will color image segmentation techniques into three categories, and to the system were summarized, analyzed the advantages and disadvantages of each method.)

核Fisher鉴别分析方法（KFDA）。KFDA方法的基本思想是首先将原始训练样本通过一个非线性映射 映射到某一高维(可能是无限维)特征空间F中，然后在F中执行Fisher鉴别分析。(Nuclear Fisher discriminant analysis method (KFDA). The basic idea of KFDA method is the first original training data by a nonlinear mapping  mapped to a high dimensional (possibly infinite dimensional) feature space F, then F in the implementation of the Fisher discriminant analysis.)
