关于speckle 去噪的一种很新的方法，基于流行的SRAD方法改进的。(The reference of thic package is On the Estimation of the Coefficient of Variation for Anisotropic Diffusion Speckle Filtering)

说明：  自己写的fft的应用实例，包括对一维振动信号分析，对二维图像频谱分析。(The application examples of FFT written by myself include one-dimensional vibration signal analysis and two-dimensional image spectrum analysis.)

说明：  本程序基于Matlab,初步实现图像增强的基本操作,实现 图像明暗度调整， 图像旋转，更改颜色显示方式，直接灰度调整，图像求反，动态范围压缩，显示原始图像直方图，直方图均衡化，滤波增强等功能(This procedure based on Matlab, the initial realization of the basic operation of image enhancement, image brightness adjustment, image rotation, change the color display, direct gray-scale adjustment, for anti-image, dynamic range compression, display the original image histogram, histogram equalization , enhanced features such as filtering)

关于导频的算法，可以给一些新手提供一些帮助，但是不敢保证一定正确，请见谅(About pilots algorithm can give some newcomers to provide some help, but can not guarantee a certain right , please forgive me)

图标生成器可以将易支持的图像格式文件转换成需要的图标，并能进行图标背景透明等编辑。(Icon generator can be easily supported image format files converted to the desired icon , and can carry out other editing icon background transparent .)

圆形，孔型工件的尺寸测量，主要采用canny算子检测边缘，并进行亚像素细分，还有GUI，测量精度在0.1mm(Circular hole workpiece size measurement using canny operator edge detection and subpixel, as well as GUI, measurement accuracy of 0.1mm)

分段函数的图形画法。用matlab画分段函数，并有图形结果，大家可根据需要修改方程(Sub-function graphic painting. Matlab piecewise function with the painting, and graphic results, we can modify equation)

编程实现二维8*8图像块的DFT，DCT变换 输入一副RGB图像，将其转化为YCbCr颜色空间，然后对Y分量做分块DFT变换，保存为灰度图像，统计计算时间 编程实现8*8块DCT变换,然后分别显示，当使用64个DCT系数里面的一些系数进行重构，比较其质量；同时熟悉采用FFT来实现DCT变换的思想，并显示2维8*8DCT变换的基函数图像(Programming the DFT, DCT transform of two dimensional 8*8 image block Input a pair of RGB images, transform it into YCbCr color space, then divide the Y component into block DFT transform, save as gray image, and calculate the calculation time The 8*8 block DCT transform is implemented by programming, and then it is shown that when using some coefficients in 64 DCT coefficients, the quality is reconstructed. Meanwhile, the idea of DCT transformation is familiar with FFT, and the base function image of the 2 dimensional 8*8DCT transform is displayed.)
