说明：  轻量级的三维画图控件，便于C/C++或C#等平台/语言中引用和开发(Lightweight 3D drawing control, convenient for reference and development in platforms / languages such as C/C++ or C#)

光线跟踪算法，能显示基本图形（球形，立方体，墙面），实现阴影，高光，反射，折射等效果(Ray tracing algorithm, can display basic graphics (sphere, cube, wall), to achieve shadows, light, reflection, refraction and other effects)

MPEG解码源代码。转载中国程序员网络，提供该代码。(MPEG decode)

P-LDA算法的代码，2009年的最新刊物的文章，较新的改进算法，供大家学习交流！(Perturbation LDA)

说明：  以python语言为平台，对机载激光雷达原始数据Las格式和txt格式进行读取，并根据信息熵确定维度特征计算的最佳邻域半径，最后计算得到最佳邻域半径和最佳维度特征值(Based on Python language, the Las format and TXT format of airborne lidar raw data are read, and the optimal neighborhood radius is determined according to the information entropy. Finally, the optimal neighborhood radius and the optimal dimension eigenvalue are calculated.)

将一个灰度图像分解成为八个位平面 然后再合并起来 可以对每一个位平面实现不同的处理(A gray level image is decomposed into eight bit plane and then combined to each bit plane to achieve different treatment)

说明：  使用matlab对人体运动进行的简单的目标跟踪，使用卡尔曼滤波(Using matlab to human movement of the simple target tracking, the use of Kalman filter)

GAC evolves the level set function according to geodesic active contour model(GAC evolves the level set function accordi Vi to geodesic active contour model)

这是一个人脸识别的程序，先对图像预处理，然后用PCA进行特征提取。(This is a face recognition process, first on the image pre-processing, and then use PCA for feature extraction.)
