2-D wedgelet transform using top-down quadtree decomposition

说明：  提出了一种基于随机森林的局放特征优选新方法。结果证明，随机森林算法是一种有效的电缆局放特征优选方法，并有望推广到其他电力设备局放的特征寻优。(A new method based on Stochastic Forest for local feature selection is proposed. The results show that the stochastic forest algorithm is an effective method for feature optimization of Cable Partial discharge, and it is expected to be extended to other power equipment partial discharge feature optimization.)

mathcad的二阶低通滤波器模型，bode图(Second-order low-pass filter model)

在vc++6.0环境下，基于OPENGL实现图形学设计内容。包括实现五边形到五角星的动态变换；利用DDA、中点画线法、Bresenham算法画直线；利用中点画圆法、Bresenham算法画圆；利用栅栏填充、扫描线填充实现多边形内部颜色填充；以及实现二维图形、三维图形的平移、放大、缩小、对称、旋转、错切等基本图形变换。(In vc++6.0 environment, we design content based on OPENGL. It includes the dynamic transformation of Pentagon to pentagonal star, using DDA, middle point drawing and Bresenham algorithm to draw straight lines; using middle point drawing circle method and Bresenham algorithm to draw circle; using fence filling and scanning line filling to fill in polygon interior color filling; and realizing the translation, enlargement and reduction of two-dimensional graphics and 3D graphics. Basic graphic transformation, such as symmetry, rotation, and error cutting.)

说明：  SIFT源码，底层代码编写，有较完整的步骤和每一步的说明，对于sift初学者特别有帮助(Sift source code, the underlying code, there are more complete steps and each step of the description, especially helpful for sift beginners)

一个用LABVIEW构建的数据采集的例子，很好的，一起学习。-Used to build a LABVIEW data acquisition examples of very good to learn.

读出autocad图形数据库中的实体并将实体类名写入excel-read graphical database entities of the entity type who would write excel

JILRuntime A general purpose, register based virtual machine (VM) that supports object-oriented features, reference counting (auto destruction of data as soon as it is no longer used, no garbage collection), exceptions (handled in C/C++ or virtual machine code) and other debugging features. Objects and functions can be written in virtual machine code, as well as in C or C++, or any other language that can interface to C object code. The VM is written for maximum performance and thus is probably not suitable for embedded systems where a small memory footprint is required. Possible uses of the VM are in game development, scientific research, or to provide a stand-alone, general purpose programming environment.
