文件中是改进的hausdorff距离匹配算法，避免了外部离散点的干扰，优化了计算方法，实现起来更加完美。(In the File,there is the improved Hausdorff distance matching algorithm, avoiding the interference of external discrete points, method, realizes more perfect.)

视频图像处理，可以实时处理视频数据，包括canny算子，边缘检测等(video image processing, real-time processing video data, including the canny operator, edge detection, etc.)

BP神经网络图像分类程序,代码很好懂，适合初学者。样本选的不是很大。(BP neural network image classification procedures, code easy to understand for beginners. Sample selected is not great.)

说明：  去除图像中的横向条纹，能有效恢复出原始图像(remove images of horizontal stripes, can be effectively restored from the original image)

MSTAR数据库中的部分SAR图像，大小限制只传12张，分辨率较大约为1476*1784，适合SAR图像的压缩恢复处理(MSTAR part of SAR image size limit only pass 12, higher resolution of about 1476* 1784, for compressed SAR image restoration processing)

图形voronoi图的自动生成算法，用vc做，是基于一般图形voronoi图的算法，结合数字图形处理里的轮廓跟踪算法，使一般图形voronoi图能够根据不同的生成元总动生成。(Graph voronoi diagram automatic generation algorithm, using vc do is based on the general graph voronoi diagram algorithm, combined with digital image processing in the contour tracking algorithm, the general graph voronoi diagram to the total depending on the generator automatically generated.)

本文件用matlab 语言，对kalman滤波的方法进行仿真，画出来原始曲线，观察值，和跟踪曲线，会对初学者有很大的帮助！(this document using Matlab language, Kalman filtering method simulation, sketching out the original curve, observed values, and tracking curve, beginners will be of great help!)

一个很有用的SAR图片，可用于SAR图像的目标识别(A very useful SAR image can be used for target recognition SAR image)

说明：  matlab生成的fig图纸转换为DXF文件(Converting fig drawings generated by MATLAB into DXF files)
