qt 二维图形变换实现源代码

matlab图像处理函数集，系统总结matlab在图像处理中的图像输入、处理（滤波、增强）、分析（边缘检测）、输出等方面的内容-matlabmatlab

这是一个应用计算机图形学知识进行消隐的程序。所绘制的三维图形是一个房子-This is an application of computer graphics knowledge blanking procedures. The three-dimensional graphics rendering is a house

使用opencv写的图像旋转与缩放程序，对初学ｏｐｅｎｃｖ的人很有用-The use of written opencv image rotation and scaling procedures, the people of learning useful opencv

aotucad的VBA例程集，里面很多实例，非常的实用。-aotucad set of VBA routines, which in many instances, very practical.

实例示范采用VB开发CAD的各个方面。包括连接CAD、操作CAD数据库、实体操作以及CAD事件应用。共44个实例-Model examples using VB to develop all aspects of CAD. Includes the connection to CAD, operate CAD databases, operating entities, as well as the application of CAD events. A total of 44 examples

本源码实现了一个在3D编程中很重要的四元数的类。在写这个类前提还包括对三维空间中向量类，以及4*4矩阵的运算。四元数对于三维模型的旋转能够很好的计算。-The source to achieve a 3D programming in a very important class Quaternion. At the time of writing the premise of this class also includes three-dimensional vector space categories, as well as 4* 4 matrix arithmetic. Quaternion for the rotation of three-dimensional model can be well calculated.

计算图像直方图的统计特征，包括均值，方差，熵，三阶矩等。-image histogram calculated the statistical characteristics, including mean, variance, entropy, such as third-order moments.

一个关于JPEG图形图像处理的隐写嵌入工具-A JPEG graphic image processing embedded steganography tools

这是一个比较好的基于主元分析PCA的代码，个人觉得很有价值。-This is a good principal component analysis PCA-based code, personally feel very valuable.
