我自己做的一个图形系统，是我们的图形学课程设计

24位真彩图像转换为256色灰度图，很好用的程序-24-bit true color image is converted to 256-color grayscale, good use of the procedure

用vb.net编写的拼图源码，非常好，值得借鉴学习。-vb.net prepared with the puzzle source, a very good, it is worth learning from.

在一幅图像的背景中加入水波，让人能感觉到有水文的存在-an image in the context of accession to the water currents, people can feel the presence of a hydrological

这是特效图片的控制代码，你可以轻松的实现窗口特殊效果，里面有VB,VC,DEPHI三种语言分别实现的代码。-This is the magic pictures control code, you can easily achieve special effects window, and they VB, VC, DEPHI three languages to achieve code.

VC实现抓屏功能，通过操作键盘的来实现，能实现多次的抓图，并保存为BMP的文件-VC realize screenshots feature of the keyboard to achieve, to achieve a number of drawings, and saved as BMP documents

一种实现读取位图的方法，适合初学者-bitmap approach for beginners

bigscro

detcoef2 提取二微小波分解高频系数 appcoef2 提取二维小波分解低频系数 wthresh 进行软阈值或硬阈值处理 wthcoef2 二维信号的小波系数阈值处理 ddencmp 获取在消噪或压缩过程中的默认值阈值-detcoef2 from two high-frequency micro-wave decomposition coefficient appcoef2 extract 2D wavelet decomposition low-frequency coefficients wthresh threshold for soft or hard threshold 2D signal processing wthcoef2 the wavelet coefficients threshold processing ddencmp access to the denoising or compression of default threshold

这个程序实现了图像的滤波，经过滤之后，图像噪点可以被去除-This procedure realize image filtering, followed by filtering, image noise can be removed

利用GDI绘图程序，使用API绘图，效率高，通用性好.-Use GDI drawing program, use the graphics API, high efficiency, universal good.
