圆检测

此程序是无损检测中匹配追踪算法的源代码，有很好的去噪效果.(This program is a non-destructive testing in the matching pursuit algorithm source code, there is a good de-noising effect.)

说明：  声呐或者雷达系统发射信号后，通过波束形成算法对两个目标（方位分别为theta1、theta2）回波进行仿真，经过相位补偿，可以看出图像有两个波峰，波峰处指向性函数峰值最大，峰值所对应的的角度值即为目标的方位角。所以该程序对数字波束形成（DBF）的原理进行了仿真，适合初学者掌握阵列信号处理中数字波束形成的原理。(After the sonar or radar system transmits the signal, the echo of the two targets (the azimuth is theta1 and theta2 respectively) is simulated by the beamforming algorithm. After the phase compensation, it can be seen that the image has two peaks, the peak of the directivity function is the largest, and the corresponding angle value of the peak is the azimuth of the target. So the program simulates the principle of DBF, which is suitable for beginners to master the principle of DBF in array signal processing.)

说明：  OpenGL的示例文件。上课时介绍用的示例文件，内含exe文件可直接运行。(OpenGL's sample file. Sample files for introduction in class, including exe files, can be run directly.)

说明：  频域滤波器器的一些相关实验和滤波器的实现（包括理想低通，Butterworth低通，高斯低通，理想高通，Butterworth高通，高斯高通滤波器）(Some related experiments of frequency-domain filter and Realization of filter (including ideal low-pass, Butterworth low-pass, Gauss low-pass, ideal high pass, Butterworth high pass, Gauss high pass filter))

自己写的中值滤波剔野程序，用于信号野值剔除。很简单，其中算法可替换(Write your own wild tick median filtering program for the signal, excluding outliers. Very simple algorithm which can be replaced)

标记分水岭的matlab程序。分水岭变换就是指将原图像转换为一个标记图像, 其中所有属于同一集水盆的点均被赋予同一个标记, 并用一个特殊的标记来标识分水岭上的点(Marking a watershed in the matlab program. Watershed transform refers to the original image is converted to a Tagged Image, which all belong to the same set of points were given a basin with a marker, and a special marker to identify the point of a watershed)
