Gradients

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)

四种压缩传感的重构算法，StOMP,BP,OMP,block_omp(Four kinds of compressed sensing reconstruction algorithm, StOMP, BP, OMP, block_omp)

生成voronoi图,生成voronoi 2D图形。(creat voronoi diagram)

改进的帧间差法运动目标追踪算法,比以前的经典算法有改善，不会出现边框锁定到边远的情况(Improved inter-frame difference method moving target tracking algorithm)

在matlab平台生成二维码，对理解二维码的编码过程有一定帮助(Generating QR code on MATLAB platform will help to understand the encoding process of two-dimensional code.)

说明：  几何偏微分方程方法应用于曲线演化的一个小程序，这里是一个matlab的源程序，不是十分复杂，显示了一个哑铃形状的曲线演化的过程(geometric partial differential equations method has been applied to the evolution of the curve of a small program here is a source of Matlab, is not very complex, and shows a dumbbell-shaped curve of the evolutionary process)

说明：  本例使用JAVA语言实现了图片的模糊与锐化，详细的注释请看源代码的注释。谢谢支持！(cases the use of the Java language and blurred images sharper and detailed annotations Look at the source code of the Notes. Thank you support!)
