显示渐变色文本的程序

绘制曲线，可以很直观的描绘曲线，是不可多的好代码-draw line

这是一个3D的圆柱体的演示-This is a 3D cylinder demo

用matlab来制作卫星绕地球做周期运动的动画，改变卫星的角速度的初值，可以画出圆形，椭圆形，逃逸轨迹。-Using matlab to produce satellites orbiting the earth to do periodic motion animation, change the initial angular velocity of the satellite, you can draw round, oval, escape trajectory.

3d地形模型,空格键可以停止/开始动画，回车键随机生成新的地形-3d terrain model, the space bar can stop/start animation, the ENTER key randomly generate new terrain

本程序支持BMP图象的拉普拉斯处理-supported the BMP image processing Laplace

图形学和数据结构的一些算法 还有图形学的一些算法的演示-graphics and data structure of the algorithm there are some graphics algorithm demo

This the fascade design pattern example. You can find its descirption in the GoF book.-This is the fascade design pattern example. You can find its descirption in the GoF book.

本代码实现了SIFT算法，首先获得差分图像尺度空间，寻找局部极值点，找到关键点，然后，对关键点生成特征描述符。实验效果很好。

一个图像检索系统的源代码，一个开发好的系统，供大家参考-an Image Retrieval System source code to develop a good system for reference

内置虑镜功能，包括获取图像的属性，锐化，模糊，浮雕等功能．可以缩放，优化图片．打开图片带预览功能,使用了gdiplus,能处理gif,bmp,jpg,png图片,处理速度也不错-consider mirror embedded functions, including access to the image attributes, sharpening, blurring, relief and other functions. Can zoom, photo optimization. Photo opened with preview function, use the gdiplus to handle gif, bmp, jpg, png images, processing speed is not bad
