运用微粒群算法求解改进的二维熵最大值算法，对于医学图像分割非常有用-Using the PSO algorithm to calculate the maximum of the improve 2D entropy value

可以方便快捷的提取图形轮廓，可以自己上传图片进行提取-Can be convenient and efficient contour extraction graphics, you can upload images to extract their own

应用背景D3D9基于HLSL的粒子系统，很不错的例子关键技术D3D9、HLSL、C++、DirectX，基于HLSL的语言的，使用的是windows平台，基于directx的库，实现了粒子系统的效果，效率比较高

这是用VC6.0编写的绘制三次Bezier曲线的程序，使用MFC框架文档视图结构。程序除实现三次Bezier曲线的绘制，还实现了点，直线，圆的绘制，可做为学习计算机图形算法的参考。与其它Bezier曲线绘制程序的不同是，本程序实现了Bezier曲线上型值点的计算显示。程序中编写了Bezier曲线类来完成Bezier曲线的绘制，并能对绘制的曲线数据进行保存与打开。对学习文件操作也有一定帮助。这是我第一次上传源码，有什么不妥之处还请管理员指点。谢谢！-VC6.0 prepared by the cubic Bezier curve drawing procedures, use MFC framework document View structure. In addition to procedures to achieve cubic Bezier curve drawing, but also realized the point, line, round mapping, can be used as learning computer graphics algorithm reference. And other Bezier curves of different procedures, The program of Bezier curve-point value calculations show. Procedures prepared Bezier curves like to complete the Bezier curve drawing, and is able to draw the curve data preservation and open. Operation right to study the documents will also help. This is the first time I uploaded the source code, what is wrong with this manager also requested guidance. Thank you!
