说明：  主要用于遥感图像道路信息提取，能得到很好的效果。(It is mainly used to extract road information from remote sensing images and can get good results.)

一些常用的图像处理评价指标，处理后图像对比度，边缘剩余数，处理前后图像的相似性....(Some commonly used image processing evaluation, contrast, edges remaining number of similarities ....)

一个基本的拉格朗日插值法示例，做出了图像帮助直观理解(Examples of Lagrange interpolation)

针对高分辨率遥感图像进行的道路提取，效果还行。(The road extraction for high resolution remote sensing images is good.)

自己编写fft2和ifft2程序并进行快速傅里叶变换试验(fft2 and ifft2)

说明：  本代码可以载入超声图像，然后通过标注连通区域，自动截取最大连通区域对应的图像部分，达到去除四周标注的目的(After loading the ultrasonic image, the image part can be automatically cut off to remove the surrounding annotation)

波束空间DOA的估计,从图中可以很好的看出角度的估计还是可以的。(Beam-space DOA estimation, from the figure we can see the point of a good estimate is still possible.)

说明：  K近邻(KNN)平滑滤波器算法，包括椒盐噪声和高斯白噪声下平滑处理的结果(K-Near Neighbor (KNN) Smoothing Filter Algorithms, Including Smoothing Processing Results under Salt and Pepper Noise and Gauss White Noise)

读取gpr数据，并且对数据进行成像，没有进行任何数据处理(Read the GPR data and image the data without any data processing)

zemax非序列下gaussian光束的matlab程序（包括zemax演示源文件）(zemax sequence under non-gaussian beam matlab program (including zemax demo source files))
