说明：  对图像纹理特征进行提取，包括灰度共生矩阵、Lbp、小波等(Texture feature extraction of image, including gray level co-occurrence matrix, Lbp, wavelet and so on)

说明：  三种emd去噪方法：1、直接使用小波阈值，进行硬阈值去噪；2、使用具有emd分解特性的阈值去噪；3、emd分解后的平移不变去噪。(Three kinds of EMD denoising methods: 1. Direct use of wavelet threshold for hard threshold denoising; 2. Use of threshold denoising with EMD decomposition characteristics; 3. Translation invariant denoising after EMD decomposition.)

检测图形中的直线，在程序中稍微改动，即可检测多条直线(Detection of graphics in a straight line, a slight change in the procedure, can detect more than a straight line)

matlab实现的DBSCAN聚类分析，通过文件输入数据，不同的颜色代表一类数据(Matlab implementation of DBSCAN clustering analysis, through the document import data, different colors represent a category of data)

基于阈值分割的运动车辆检测跟踪，在视频中按灰度阈值不同进行图像分割，并标记结果。(Threshold-based segmentation to track the movement of vehicles detected in the video by a different gray level threshold for image segmentation, and mark the results.)

说明：  基于bp神经网络的车牌识别，运行时先运行nn.进行训练(License Plate Recognition Based on BP Neural Network)

模拟圆管焊接时的移动热源，热源模型为双椭球热源，运动轨迹为环形(Simulated moving heat source pipe welding heat source model for the double ellipsoid heat source, an annular trajectory)

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.)
