k均值聚类分析。K-means clustering analysis(K-means clustering analysis)

itti算法进行感兴趣区域的选择，方法较好，可以直接运行。(itti algorithm select the region of interest ,and this program can run directly)

说明：  用于去除背景，得到原图与背景相减的图像并二值化(boundaries defects and improve the quality of remote sensing images and improve the visual effects))

程序功能是把一副倾斜的文字图像矫正过来，通过边缘检测再进行霍夫变换完成(The program function is to correct a skewed text image.)

几种经典的图像平滑去噪算法程序，其中包括小波软阈值和硬阈值处理。还附送三个图像质量评价程序(several classic image denoising smoothing algorithm procedures, which include thresholding wavelet soft and hard threshold processing. Also attached three image quality evaluation procedures)

画矩形的代码，包含各种算法，具体的自己看吧，这是图形处理的作业之一(Draw a rectangle of the code, contains a variety of algorithms, specifically for yourself, this is one of the graphics processing jobs)

图像去雾算法质量评价标准：均值方差，峰值信噪比及平均梯度的源代码，还有引导滤波的完整源代码。(Image quality uation algorithm defogging criteria: mean and variance, the peak signal to noise ratio and average gradient of the source code, as well as guide the filter complete source code.)

利用MATLAB处理图形图像，求曲线的曲率(Using MATLAB processing graphics demand curve curvature)

说明：  实现了离散小波变换和连续小波变换，用于小波分析。(Discrete wavelet transform and continuous wavelet transform are implemented for wavelet analysis.)

说明：  为图像分别加高斯噪声和椒盐噪声，采用中值滤波方法对受噪声干扰的图像滤波，窗口分别采用3*3,5*5,7*7；(Gaussian noise and salt and pepper noise are added to the image respectively. The median filtering method is used to filter the image disturbed by noise. The window is 3 * 3,5 * 5,7 * 7;)
