读取dxf文件，并利用opencv画出2D形状(Read the DXF file, and draw a 2D shape using OpenCV)

这个是把图像归一化的程序，原始的图片可以随意设置，效果比较好。(This is the image of the normalized program, the original pictures can freely set, the effect is good. )

用于植物叶片分类的图形界面,是Matlab源码，用BP神经网络实现(For plant leaf classification graphical interface, the Matlab source code, using BP neural network)

Freeman链码（8方向）代码，进行图像边缘的描述，可用于基于内容的图像检索系统(Freeman chain code (8 directions) code)

基于CFAR虚警率的图像分割算法，可快速对灰度图像进行CFAR检测分割。(Based on the false alarm rate of CFAR image segmentation algorithm, the gray image can be fast CFAR detection and segmentation.)

利用傅里叶变换方法自动处理正弦条纹图像，获得条纹图相位(Fourier transform method for automatic processing of sinusoidal fringe image obtained fringe pattern phase)

说明：  matlab编写的图像处理程序，用于提取图像的纹理、颜色特征。(matlab image processing procedures to prepare for the extraction of image texture and color features.)

链码直线检测，采用求取图像边界，然后边界跟踪，判别直线(Chain code line detection, to strike the image boundary, then the boundary tracking, discriminant linear)

本代码实现了基于卡方分布(nakagami 分布)的恒虚警检测(CFAR)，通过在查找表的形式，实现参数估计和阈值估计，完成对目标的检测。(The code based on the chi-square distribution (nakagami distribution) of the CFAR (CFAR), through the form of a lookup table to achieve the threshold parameter estimates and estimates to complete the target detection.)

能够对采集到的连续信号进行傅里叶变换，以进行后续处理(It can carry out Fourier transform to collect continuous signals for subsequent processing.)
