用matlab编程工具,编写具有操作界面的应用程序,通过菜单、对话框,选项框等界面控制,对算法进行演示。需要在应用系统中实现的算法及功能包括:
1、图像增强算法
(1)灰度线形变换:亮度及对比度可以调节(通过控制参数的改变,能够实时预览变化结果);
(2)直方图均衡:可在界面上对比均衡前后的效果。
2、图像变换算法
(3)对一幅彩色图像进行DCT变换和反变换,对比结果和原图;
(4)仅保留左上角16X16的DCT系数,进行反变换,计算结果图的信噪比SNR。
3、图像分割算法
(5)采用最优阈值算法对灰度图像进行分割;
(6)用Canny算法对灰度图像进行边缘检测;
(7)用hough变换,检测边缘图像中的直线,并用不同颜色将检测出的直线叠加显示到原图像上。

classification
基于K均值算法的模糊分类器具有很好的分类效果,用它可以很准确的对训练样本进行分类. 此方法是将K均值算法应用于训练数据的聚类,对每个聚类的半径和聚类的中心都是可计算的. 而模糊系统设计方法就是用模糊度来描述聚类,
对训练数据进行高效且准确的分类.(based on K-mean Algorithm,it can Classify the original data very well!)

Welch法:Welch法对Bartlett法进行了两方面的修正:一是选择适当的窗函数w(n),并在周期图计算前直接加进去,加窗的优点是无论什么样的窗函数均可使谱估计非负。二是在分段时,可使各段之间有重叠,这样会使方差减小。(Welch method: Welch method of Bartlett method amendments in two respects: First, select the appropriate window function w (n), and in the cycle before CALPHAD directly incorporated, plus the advantage of the window, no matter what kind of window function can be so spectral estimation of non-negative. Second, when in subparagraph can overlap between paragraphs, this would reduce the variance.)
