5/3小波变换的提升算法实现以及对于什么叫做提升的介绍。由于5/3小波是整数小波，因此非常适合于DSP处理，且经过提升，小波变换的复杂度明显降低，将此代码的提升部分移植到DSP上，可以达到实时。(5/3 wavelet transform algorithm to enhance as well as what is to enhance the introduction. Since the 5/3 integer wavelet wavelet is therefore very suitable for DSP processing, and after upgrading, wavelet transform significantly reduced complexity, the upgrading of part of this code ported to DSP, we can achieve real-time.)

用vc+mapobjects开发的源代码，实现鼠标多边形的移动(with vc MapObjects development of the source code, mouse polygon mobile)

一个简单的程序，可以绘制点、线、圆、方。可以保存成一定格式的图片文件。软件最大的问题是绘图基本在对应的鼠标事件里进行，而没有在paint方法里进行，可借鉴。(A simple program, you can draw points, lines, circles, square. Can be saved into a certain format image files. The biggest problem is the graphics software basic mouse events in the corresponding conduct, but not in the paint method in the conduct, we may learn.)

draw用法。新手必看，通俗易懂，请结合工具书(draw Xinshoubikan usage, easy to understand)

off 转stl ，很好的转换软件源码。实现了off三维格式向stl三维格式转换，可用于CAD、ProE等软件对接。( Turn off to stl, good conversion software source code. Off to achieve a three-dimensional format stl three-dimensional format conversion, it can be used in CAD, ProE and other software docking.)
