对灰阶图像进行大气湍流滤波，使图像达到需要达到的效果(The atmospheric turbulence filtering is applied to the gray scale image to achieve the desired effect)

zernike亚像素识别算法，matlab实现。(Zernike sub-pixel recognition algorithm, matlab achieve.)

平台基于visual studio2015，使用opencv函数实现高斯滤波，进行图像处理(gaussian blur based on opencv)

完整的仿真了地形匹配中的TERCOM算法，包含了地形数据。(A complete simulation of terrain matching in the TERCOM algorithm, including terrain data.)

PCB板检测的大概流程如下：首先存储一个标准PCB板图像作为参考标准，然后将待检测的PCB板图像进行处理，比较与标准PCB图像的差异。根据差异的情况来判断缺陷类型。(The approximate process of PCB board detection is as follows: first, a standard PCB board image is stored as a reference standard, and then the PCB board image to be detected is processed to compare the difference between the standard PCB image and the standard image. The type of defect is judged according to the difference.)

说明：  FMCW信号处理是通过python脚本实现的，可以总结为： FMCW IF信号预处理 范围-时间地图构造（RTM） 多普勒时间地图构造（DTM） 角度时间地图构造（ATM）(FMCW signal process was implemented by python script, which can be sum up as: FMCW IF signal pre-process Range-Time-Map construction (RTM) Doppler-Time-Map construction (DTM) Angle-Time-Map construction (ATM))

在网上看到的一个在线SVR(支持向量机回归)的C++代码,希望对大家有帮助()

说明：  图像预处理以及提取图像的Tamura 纹理特征(Image preprocessing and Tamura texture feature extraction)
