在各种图形中，通过提取点的凹凸部分来鉴别曲线的特征，本节代码利用曲率关系分别提取凹点的个数，判断曲线的弯曲(In a variety of graphics, through the extraction point to identify curves convex-concave part of the characteristics of the code used in this section were extracted from concave curvature of the relationship between the number of points to determine the bending curve)

说明：  学习用的,很简单的图形界面.它是一个简单的界面,加事件,以及2D的图形绘制的例子(the study, a very simple graphic interface. It is a simple interface, plus events, and the 2D graphic example)

可以实现图像篡改检测，附带有几张图片，检测效果一般(Image tamper detection can be achieved, with pictures, the detection effect is general)

说明：  对二维数据进行变分模态分解，可用于地震数据去噪等(Variational mode decomposition of two-dimensional data can be used for seismic data denoising, etc.)

相机标定过程中，对初始得到的内外参数的进行整体优化，从而得到最佳内外参数的程序(Camera calibration process, the overall optimization of the initial parameters obtained inside and outside, resulting in the program inside and outside the parameters of the best)

通过矩阵变换，实现二维图像在给定角度下的旋转。(By matrix transformation, achieve the rotationa of a two-dimensional image in a given angle .)
