基于matlab编程开发的一段代码，实现并测试通过了nqKdOJ流程的nqKdOJ功能，适用于初学nqKdOJ者学习该算法的原理，已经编译通过了，测试正常. (Matlab-based programming development of a piece of code, implemented and tested by thenqKdOJ process functions for beginners to learn sfs principle of the algorithm has been compiled through, the tests are normal. )

基于MATLAB的椭圆拟合算法，有主程序，带结果显示图片(MATLAB-based ellipse fitting algorithm, with the main program, with results show that image)

3D FDTD 计算程序 ToyFDTD1 is a stripped-down, minimalist, 3-dimensional FDTD code that is published under the GNU General Public License. It is the first in the ToyFDTD series of codes, and it illustrates in heavily commented C and Fortran the basic tasks in implementing a simple 3D FDTD simulation.(3D FDTD computational procedures ToyFDTD1 is a stripped-down, minimalist, 3-dimensional FDTD code that is published under the GNU General Public License. It is the first in the ToyFDTD series of codes, and it illustrates in heav)

1. 图像二值化 2. 边界跟踪，去除离散点 3. 边界提取 4. 删除短边 5. 区分河流与道路 先找到桥梁，利用桥梁上的种子点 对道路进行跟踪，从而提取整条主干道。 (1 image binarization 2boundary tracking, removal of discrete points 3 boundary extraction 4 Remove the short side 5 distinguish rivers and roads the curvature is too large) First find the bridge, the bridge on the use of seed points on the road to follow, thereby extracting the whole trunk.)
