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.)

sparfilt
优点:1.对于信噪比高的信号滤波效果好;
% 2.对于边沿的保护强过阈值滤波,不会产生阈值滤波情况下的过于平滑与Gibbs现象。
%缺点:1.由于对边沿信号没做任何处理,所以边沿可能会有脉冲噪声保留下来;
% 2.计算相关系数中,如果计算出来的小波系数点位置偏差大,则相关系数计算受影响;
% 3.需要迭代运算,迭代的噪声能量阈值选取很重要,这里以开始段无信号处估计噪声;
% 4.需要迭代运算,所以运算量比阈值法大;
% 5.受分解层次影响,在大尺度上小波系数点位置偏差更大,相关系数计算不准确。
%需要具体调整的地方:1.分解的尺度;()
