在本书的最好附录中，我总结了一些对学生，教授和研究者有用的附加材料。这本书的网址https://www.360docs.net/doc/7a8637543.html,/Book包含了更新的数据集和软件，请同样访问他。
C.1 数据集
一个关键就是用富有挑战和典型的数据集来测试你算法的可靠性。当有背景或者他人的结果是可行的,这种测试可能甚至包含更多的信息(和质量更好)。
经过这些年，大量的数据集已经被提出来用于测试和评估计算机视觉算法。许多这些数据集和软件被编入了计算机视觉的主页。一些更新的网址，像CV online

http://www.nada.kth.se/cvap/actions/包含更多的行动序列。
C.2 软件资源
一个对于计算机视觉算法最好的资源就是开源视觉图像库（opencv）
(https://www.360docs.net/doc/7a8637543.html,/wiki/),他有在intel的Gary Bradski和他的同事开发，现在由Willow Garage (Bradsky and Kaehler 2008)维护和扩展。一部分可利用的函数在
https://www.360docs.net/doc/7a8637543.html,/documentation/cpp/中：
图像处理和变换(滤波，形态学，金字塔);
图像几何学的变换(旋转，改变大小);
混合图像变换(傅里叶变换，距离变换);
直方图;
分割(分水岭, mean shift);
特征检测(Canny, Harris, Hough, MSER, SURF);
运动分析和物体分析(Lucas–Kanade, mean shift);
相机矫正和3D重建
机器学习(k nearest neighbors, 支持向量机, 决策树, boost-
ing, 随机树, expectation-maximization, 和神经网络).
Intel的Performance Primitives (IPP) library, https://www.360docs.net/doc/7a8637543.html,/en-us/intel-ipp/，包含
各种各样的图像处理任务的最佳优化代码，许多opencv中的例子利用了这个库，加入他安装了，程序运行得更快。依据功能，他和Opencv有很多相同的运算处理，并且加上了额外的库针对图像视频压缩，信号语音处理和矩阵代数。
MTALAB中的Image Processing Toolbox图像处理工具，
https://www.360docs.net/doc/7a8637543.html,/products/image/，包含常规的处理，空域变换（旋转，改变大小），常规正交，图像分析和统计学（变边缘，哈弗变换），图像增强（自适应直方图均衡，中值滤波），图像恢复（去模糊），线性滤波（卷积），图像变换（傅里叶，离散余弦变换）和形态学操作（连通域和距离变换）
两个比较旧的库，它们没有被发展，但是包含了一些的有用的常规操作：
VXL (C++ Libraries for Computer Vision Research and Implemen-tation,
https://www.360docs.net/doc/7a8637543.html,/)
LTI-Lib 2 (http://www.ie.itcr.ac.cr/palvarado/ltilib-2/homepage/ ).
图像编辑和视图包，例如Windows Live Photo Gallery, iPhoto, Picasa,GIMP, 和IrfanView，它们对执行这些处理非常有用：常规处理任务，格式转换，观测你的结果。它们同样可以用于对图像处理算法有趣的实现参考，例如色调调整和去噪。
这里他也有一些软件包和基础框架对你建一个实时视频处理的DEMOS很有用，Vision on Tap(https://www.360docs.net/doc/7a8637543.html,/)提供一个可以实时处理你的网络摄像头的网页服务(Chiu and Raskar 2009）。Video-Man (VideoManager, https://www.360docs.net/doc/7a8637543.html,/处理实时的基于视频的DEMOS和应用非常有用，你也可以用MA TLAB中的imread直接从任何URl（例如网络摄像头）中读取视频。

算法C.1 C algorithm for Gaussian random noise generation, using the Box–Muller transform. C描述的利用Box–Muller 变换产生高斯随机噪声
double urand()
{
return ((double) rand()) / ((double) RAND MAX);
}
void grand(double& g1, double& g2)
{
#ifndef M_PI
#define M_PI 3.14159265358979323846
#endif // M_PI
double n1 = urand();
double n2 = urand();
double x1 = n1 + (n1 == 0); /* guard against log(0) */
double sqlogn1 = sqrt(-2.0 * log (x1));
double angl = (2.0 * M PI) * n2;
g1 = sqlogn1 * cos(angl);
g2 = sqlogn1 * sin(angl);
}
高斯噪声的产生。许多基本的软件包产生一些不同的随机的噪声(例如运行在unix上的rand())，但是并不是所有的都有高斯随机噪声发生器。计算一个离散随机常量，你可以用Box–Muller transform (Box and Muller 1958)，他的c代码在算法C.1中给出了，注意这个运行结果是返回一对随机变量。相关的产生高斯随机变量的方由Thomas, Luk, Leong et al. (2007)提出。
伪彩色产生。在很多应用中，很方便给图像加上标记（或者给图像特征比如线）。一个最简单的方式就是给不同的标记不同的颜色。在我的工作中，我发现用RGB立体色彩系给不同的标记赋予标准均匀的色彩是很方便的。
对于每一个（非消极）标记值，consider the bits as being split among the three color channel，例如对于一个比特值为9的值，
这个值可以被标记为RGBRGBRGB，获得三基色中的每一种颜色值后，颠倒比特值，结果是低位的比特值变化的最快。
实际上，对于一个八比特的颜色通道，这个比特值的颠倒可以被存在一个表或者一个存储提前计算好的记录有由标记值向伪彩色的改变的完整表。
图8.16 显示了这样一个伪彩色绘制的例子.
GPU实现
GPU的出现，可以处理像素着色和计算着色，导致了实时应用的快速计算机视觉算法的发展，例如，分割，追踪，立体和运动估计（(Pock, Unger, Cremerset al. 2008; Vineet and Narayanan 2008; Zach, Gallup, and Frahm 2008）。一个好的资源来学习这些算法就是CVPR 2008 上关于Visual Computer Visionon GPUs的workshop。
