独立分量分析

说明：  利用matlab的gui设计的带有输入和输出功能的界面图形，可视性很强，学习非常值得(The interface graphics with input and output functions designed by GUI of MATLAB have strong visibility and worth learning.)

图像轮廓特征提取算法源码，用MATLAB软件实现，针对灰度图像有效(Contour feature extraction algorithm source code, using MATLAB software for gray-scale image of effective)

产生高斯白噪声，已知期望和方差，这样就生成了一组随机数据(Generated white Gaussian noise of known expectation and variance, thus generating a set of random data)

将一个灰度图像分解成为八个位平面 然后再合并起来 可以对每一个位平面实现不同的处理(A gray level image is decomposed into eight bit plane and then combined to each bit plane to achieve different treatment)

计算机图形学，扫描线种子填充算法,填充算法，填充算法(dd )

基于rtklib计算加入北斗的单点定位及差分定位(single PP and DGNSS using BEIDOU based on RTKLIB)

光线跟踪算法，能显示基本图形（球形，立方体，墙面），实现阴影，高光，反射，折射等效果(Ray tracing algorithm, can display basic graphics (sphere, cube, wall), to achieve shadows, light, reflection, refraction and other effects)

说明：  modis一般是hdf数据，使用MRT（MODIS Reprojection Tool）工具可以将数据装换为.tif格式以及提取拼接(Modis is commonly HDF data, and the data can be reprojected to the.tif format and outprojection using the MRT (modis Reprojection Tool))

将曲线轮廓中的B-样条曲线通过最小二分法转换成一组能保持曲线轮廓形状的小折线。这样，原有的字体轮廓数据就从用曲线轮廓表示转变为用多边形表示，即用一组点及其先后顺序来描述轮廓。(Profile to Polygon)

说明：  以python语言为平台，对机载激光雷达原始数据Las格式和txt格式进行读取，并根据信息熵确定维度特征计算的最佳邻域半径，最后计算得到最佳邻域半径和最佳维度特征值(Based on Python language, the Las format and TXT format of airborne lidar raw data are read, and the optimal neighborhood radius is determined according to the information entropy. Finally, the optimal neighborhood radius and the optimal dimension eigenvalue are calculated.)
