适用于任意图像中轮廓的直线段检测与描绘，对于公路车道直线检测具有良好效果。(Linear segment detection and description for contours in arbitrary Images,it has good effect for straight line detection of highway lanes.)

CAD文件dxf格式转化为G代码的软件，非常好用，而且源码开源的，可以作为学习参考的例子(Dxf format CAD file into a G-source software, very easy to use, and the source code open-source can serve as a useful example to study)

说明：  利用c语言快速实现各类小波变换，案例丰富(Using C language to realize all kinds of wavelet transform quickly, with rich cases)

说明：  这个文件中包含了三种图像相似度的计算方法，分别是灰度分布计算方法、颜色分布直方图计算方法、还有结构相似度SSIM计算方法。(This file contains three image similarity calculation methods, namely, gray distribution calculation method, color distribution histogram calculation method, and structure similarity SSIM calculation method.)

phog算法的matlab实现，hog特征用于对象识别，比如人脸识别、人体识别。(phog algorithm matlab achieve, hog characteristics for object recognition, such as face recognition, human identification.)

IDL读取txt，txt第一列是纬度，第二列是经度，第三列是DN值， 坐标转行列号 ，并以图像的形式输出(IDL reads TXT. The first column of TXT is latitude, the second column is longitude, and the third column is DN value. The coordinate turns the line and column number and outputs it in the form of image)

本算法包括区域生长法和形态学后处理算法，功能实现了皮肤镜图像的病变区域分割，准确度很高，后处理算法对原图的影响很小；(This algorithm includes region growing method and morphological post-processing algorithm. It can segment the lesion area of dermoscopic image with high accuracy, and the post-processing algorithm has little influence on the original image.)

基于背景减除的单目标跟踪方法在Matlab中的实现，包含测试用avi文件(Background subtraction based on a single-target tracking method in Matlab, implementation, including test avi file)

说明：  绘制二维nurbs曲线，可以通过改变控制点或者权重从而改变图形的形状。(Draw a two-dimensional nurbs curve that changes the shape of a shape by changing the control point or weight.)
