项目使用流程:

1. 运行kruskal.exe

2. 按照流程输入图片路径(bmp格式)和梯度阀值(默认为200)

注: 阀值越高, 轮廓越稀疏

3. 运行fourier.exe

4. 按F5开始绘制

-----------------------------------以下内容可以不看-----------------------------------

fourier.exe使用进阶教程:

1. 按顺序点击屏幕形成点阵

2. 按Z撤销一个点

3. 按X恢复一个点

4. 按Esc清除所有点

5. 按F5开始/结束绘制

6. 按F1显示/隐藏点阵

注: 绘制时, 程序默认不显示点阵, 此时按F1以显示点阵

7. 按F2隐藏/显示矢量

8. 按空格暂停绘制

9. 可以修改data.in以设置初始点阵

注: kruskal.exe会将运算结果输出到data.in中

## 编译指令

对于kruskal.cpp:	g++ kruskal.cpp -o kruskal -lgdi32

# English

Project usage process:
1. Run the kruskal.exe

2. Input image path (the bitmap format) and gradient threshold (default is 200) according to the process

Note: the higher the threshold, the more sparse the contour

3. Run the Fourier.exe

4. Press F5 to start drawing

-----------------------------------You can skip the following-----------------------------------

fourier.exe using advanced tutorials:
1. Click the screen in order to form a dot matrix

2. Press Z to undo a point

3. Press X to restore a point

4. Press Esc to clear all points

5. Press F5 to start/end the drawing

6. Press F1 to show/hide the dot matrix

Note: when drawing, the program does not display the dot matrix by default. Press F1 to display the dot matrix

7. Press F2 to hide/show the vector

8. Pause drawing by space

9. You can modify data.in to set the initial lattice

Note: kruskal.exe will output the calculation result to data.in

## Compiled instruction

For kruskal.cpp:	g++ kruskal.cpp -o kruskal -lgdi32

For fourier.cpp: 	g++ fourier.cpp -o fourier -lgdi32 -mwindows

## Introduction to algorithms

For kruskal.cpp: edge operator, Delaunay triangulation algorithm, kruskal minimum spanning tree algorithm, Douglas-Peucker algorithm;

For fourier.cpp: fast Fourier transform algorithm, inverse discrete Fourier transform algorithm;
