- 介绍各种形体的表示以及数据结构,实现包括Koch曲线和Koch雪花,Sierpinski地毯,L-S分形树的编程实现。-Introduced a variety of physical representation and data structure, to achieve, including Koch and Koch snowflake curve, Sierpinski carpet, LS Fractal Programming tree.
PSNR
- 该算法主要用来计算PSNR值,能够求出生成图像与原始图像的客观对比-Image inpainting refers to reconstructing the corrupt regions where the data are l destroyed.A primary class of the technique is to build up a partial differentia uation,consider it as a boundary problem,and solv

Single-like-rear-space-rendezvous
- 我是采用java来编写这个程序的:java是我们目前正在学习的一门语言 ,采用这一语言正好可以加深我对它的理解。 程序的主体是采用一个do……while的循环。在这个循环中,我分别建立了两个数组,存储误差方程系数阵A和自由向量L。其余关于平差解算,我采用的是一个矩阵运算包,并调用其中的函数来实现。我的初始数据是直接嵌入在程序中,而结果数据则以一个TXT文档的形式输出。用来完成单像后方空间交会。 -I use java to write the program: Java is a lan
