说明：  我把以前写的 C# 版的Rose 共享出来供别人学习参考。很具有学习参考价值主要涉及 GDI+ ,软件架构，和界面。对初学者很有帮助(I have previously written in C# Version of Rose shared out for others to learn from the reference. With learning reference value is mainly related to GDI+, Software architecture, and interface. Very helpful for beginners)

说明：  气球式提示栏当运行有错误或者有错误时会出现气球提示栏卡通化的设计(Balloon tips column when running error or an error occurs when the balloon cartoon prompted the design of column)

维纳滤波Matlab代码 1 可以直接作为函数调用； 2 可以减少图像的块效应，以及平滑图像。(Wiener Filter Matlab code can be used directly as a function call 2 blocks can reduce the image effects, and smoother image.)
