java编写的关于图形的简单的粒子系统

画一条直线和立方体的源代码，可以通过改变参数，来改变图形的大小。-Draw a straight line and the cube of the source code, you can change the parameters to change the graphic size.

SIFT特征提取与匹配,根据代码可以实现各种功能，非常全面-SIFT feature extraction and matching

原作者的pca-sift程序，对Lowe的sift做了一定改进。-The original author of the pca-sift procedures, Lowe" s sift made certain improvements.

用vc显示JPEG文件格式，希望有帮助对大家，-with vc display JPEG file format, with the hope of helping to everyone,

在原始图像buf上画直线的算法，便于观察调试，无错误-the original image buf painted linear algorithms facilitate the observation of debugging, error-free

计算机图形学三维变换，包括旋转与缩放，TC2.0下编译-Three-dimensional computer graphics transformations, including rotation and scaling, TC2.0 compiled

者仍然是一个计算机图形学中对直线的裁剪算法。。。供大家参考-Who is still a computer graphics algorithm for straight line cutting. . . For your reference. .

用Java实现的图像教学程序，涵盖大部分基本图像处理技术：（1）图像几何变换（图像翻转、旋转、缩放）；（2）色彩变换（灰度直方图，RGB->YSH变换，对比度调整，色彩增强，灰度均衡）；（3）卷积（锐化、柔化、边缘提取、中值滤波）；（4）频率变换（快速傅立叶fft，小波分解重构）-A teaching program which implements in Java. It includes most essential image processing technology. 1. Geometry Transform(Flip, Rotate, Scale) 2. Color Transform(Histogram, RGB-YSH Translate, Contrast, Level, Equalize in gray) 3. Convolve (Sharpness, Smooth , Edge enhancement, Mean) 4.Frequence Transform (FFT, wavelet reconstruct)
