用MATLAB 2017b GUI写的一款小工具。
无论是课堂、会议上随手拍的照片，还是阅读文献的截图，很快可以提取到曲线的原始数据点作为学习研究的参考。
主要思路是：
1）预处理：裁剪选区、透视变换（交互式点击四个角点）；
% 得到以坐标轴为边界的矩形图像
2）坐标变换：输入X、Y轴起始坐标，选择坐标类型（可选择线性坐标系或者对数坐标系）；
% 将像素坐标转换为图片坐标
3）点击目标曲线上任一点自动识别颜色并分割，灰度图像直接阈值分割；
% 除目标曲线外全部清空
4）输入希望得到的数据点数，自动等间距捕捉曲线上的点；
% 等间距扫描取相应点数
5）导出所捕获点的EXCEL数据表。
% 所有数据点存储在EXCEL中
涉及到一些线性代数和数字图像的知识，基本都是经典的图像算法，为了交互友好自己添加了一些 “算子” 做成了Slider。
直接上例子：
（1）随手画的一张，测试透视变换、图像分割、去噪效果。
（2）测试目标颜色过滤效果。
（3）复杂曲线数据点生成测试。
（4）复杂曲线颜色过滤测试
处理结果比对：
（1）
（2）
点击选择蓝色曲线所得结果。
（3）
（4）
