一个读取DXF文件的工具，有示例，有源代码，对某些需要与Autocad进行图形学接口编程的朋友有十分重要的工具，我可以千般辛苦找来的。(a read DXF files tools, example, the active code, certain needs and Autocad graphics interface for programming and friends very important tool, I can offer all kinds of hard to find.)

1. 将真彩位图转化成各色或黑白位图，进行二值化(支持多种抖动方法)处理后的位图，效果和速度极佳。 2. 将真彩或黑白位图进行 90度 , 180 度 ,270 度 高速度旋转。 (1. The true color bitmap into a colored or black and white bitmap to binary (supports multiple dithering methods) treated bitmap, effects and excellent speed. 2. The true color or black and white bitmap to 90 degrees, 180 degrees, 270-degree high-speed rotation.)

对三维图像进行配准，输入为RAW文件，输出为RAW+mha文件(3D image registration, input as RAW file, output as RAW mha file)

数字图像处理试验程序 包括图像的压缩 模糊 锐化(Digital image processing, testing procedures, including image compression blur sharpening)

一个生成NURBS曲面的程序，是在Visual下运行的(A NURBS surface generation program is run under Visual)

适合初学图形学的人,都是基本的绘图与填充及图形变换,贝页丝曲线的绘制.(graphics suitable for beginners who are basic drawing and filling and graphic transformation, Pui-page wire drawing curves.)

计算图像的质心，用图像的算发进行操作。这样可以有效的算出图像的质心(The centroid of the calculated image, with an image of the operator hair operation. This can effectively calculating the image centroid)

问题：找出一个短字符串在一个长字符串中的精确匹配。 要求：基于BWT压缩和FM索引技术的序列匹配，用Burrows-Wheeler transform算法解决该问题。(Problem: find the exact match of a short string in a long string. Requirements: BWT-based compression and indexing techniques sequence matching FM, with the Burrows-Wheeler transform algorithm to solve the problem)

关于车辆跟踪的c++程序，使用了opencv进行跟踪，采用了帧差方法效果还不错(vehicle detection)

用于各种特征提取主成分分析法，如表情提取，人脸提取，识别分类等(For a variety of features to extract the principal component analysis (pca)，Such as expression extraction, face extraction, identification classification, etc)
