介绍一下制作这个类库的流程：新建一个项目→选择 类库 → 在这个类库的基础上添加新建项 → 用户控件→添加 引用HalconDotNet → 拖一个 Halcon显示图像的HalconWindow 上去 → 改写，添加 放大 缩小的功能 完毕。(Description: halcon and C # joint programming, control function 1, support the mouse button zoom and left drag 2, support in the image after scaling, region, xld, roi can reproduce 3, support region, xld in accordance with the specified color display, and In the zoom after the recurrence of 4, support rectangle 1, rectangle 2, circle, and straight roi drawing 5, you can display the current position of the left mouse button image gray value 6, you can save the original image, or screenshots of the current window (Halcon and C # joint programming))

建立简单的层状模型，共三层，褶积合成地震记录，使得数据随机缺失30%，分别用傅里叶变换、短时傅里叶变换、s变换、小波变换对地震数据进行时频分析。(A simple layered model with three layers and convolution synthetic seismogram is established. The data are randomly missing by 30%. Time-frequency analysis of seismic data is carried out by Fourier transform, short-time Fourier transform, S transform and wavelet transform, respectively.)
