聚类有效性指标,比较全，功能比较强大，是学习聚类的好工具(Clustering Validity Indices)

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.)

程序可实现dwg文件注记的批量替换, 可根据需要进行扩展。(Dwg file program allows batch replacement Note)

knn k近邻算法，可选择欧式距离或者曼哈顿距离(knn k nearest neighbor, Euclidean distance or Manhattan can choose the distance)

自适应阈值分割代码，比较完整。C++builder编写，可运行/()

多层mie散射程序,可以模拟多层粒子的散射情况。(multi-layer mie scatter )

说明：  利用matlab对图像进行处理，通过形态学开闭运算，实现对光照不均匀啤酒瓶图像进行准确计数(The image is processed by MATLAB, and the image of beer bottle with uneven illumination can be counted accurately by morphological opening and closing operation)

We extend the well-known Shi-Tomasi-Kanade tracker by introducing an automatic scheme for rejecting spurious features. We employ a simple and efficient outlier rejection rule, called X84. Experiments with real and synthetic images confirm that our algorithm makes good features to track better
