代码-不变矩

随着这些年计算机硬件水平的发展, 计算速度的提高, 源自序列蒙特卡罗方法的蒙特卡罗粒子滤波方法的应用研究又重新活跃起来,本()

说明：  多站拼接后三维激光扫描点云的消冗处理,多站拼接后三维激光扫描点云的消冗处理(After more than three-dimensional laser scanning station splicing point cloud processing eliminate redundant, multi-dimensional laser scanning station splicing eliminate redundant processing point cloud)

图像拾取演示，精选ios编程学习源码，很好的参考资料。(Image pickup demonstration, selection of learning IOS programming source code, a good reference.)

用于绘制光子晶体光纤空气孔形状的可扩展程序。(This is a simple and expandable programm for the air hole shape of Photonic crystal fiber )

医学图像处理，实现图像分割，一基于区域生长法；二基于最佳阈值分割(Medical image processing, and image segmentation, one based on region growing method two thresholding based on the best)

说明：  使用shp文件裁剪矢量数据，可自己选择矢量文件，栅格文件，输出文件(Use SHP file to crop vector data. You can choose vector file, grid file and output file)

说明：  多尺度多方向性的剪切波Shearlet变换优于小波变换，里面包含很多例子，可以直接运行，可以用于图像去噪，分割，增强等，是一个优于小波的图像稀疏表示工具(Shearlet transform of multi-scale and multi-directional shear wave is better than wavelet transform. It contains many examples and can run directly. It can be used for image denoising, segmentation and enhancement. It is an image sparse representation tool better than wavelet transform.)

一种基于Arnold变换的图像加密技术，并且用Matlab的GUI界面设计一个用Arnold算法进行图像加密的程序。该程序实现了Arnold图像加密算法的加、解密功能，以及一些基本的图像处理功能。(A kind of image encryption technology based on Arnold transform, and use Matlab GUI interface to design a Arnold encryption algorithm. This program implements the encryption and decryption function of Arnold image encryption algorithm and some basic image processing functions.)

三维模型的网格简化算法，通过删除边来减少面片个数，同时保留图形特征(Three-dimensional model of the mesh simplification algorithm to reduce the number of patches by removing the side, while retaining graphic features)

主要功能是实现相机标定，以及实现反投误差，实现特征点的提前。(The main function is to achieve camera calibration and error to achieve the anti-investment, to achieve the feature points in advance.)
