前  言
前 言
本书介绍计算机视觉基础。计算机视觉(也称为机器视觉)的主要目标是基于由各种
相机捕获的图像内容来重建和解释自然场景(参见R. Szeliski[187])。计算机视觉系统包括
诸如卫星测绘、机器人导航系统、智能扫描仪和遥感系统之类的东西。在计算机视觉研究
中,重点是从图像中提取有用的信息(参见S. Prince [159])。计算机视觉系统通常模仿人
类视觉感知。计算机视觉系统中选择的硬件是某种形式的数码相机,被编程为近似视觉感
知。因此,计算机视觉、数字图像处理、光学、光度学和光子学之间存在密切联系(参见
E. Stijns 和H. Thienpont [184])。
从计算机视觉的角度来看,光子学是捕捉视觉场景中光的科学。图像处理研究数字图

第3章 可视化像素强度分布
  本章介绍可视化像素强度分布的各种方法(参见图3.1)。这里还包括在图像镶嵌和三角化中有用的生成点指针。换句话说,图像结构可视化展示了关于图像几何的内容。

图3.1 图3.4中组合RGB像素强度的3-D视图
  这里的基本方法是在裁剪数字图像中提供关于像素强度的2-D和3-D视图。通过裁剪彩色图像,可以获得组合的像素彩色值或同一图像内的各个彩色通道像素值的不同视图。图像裁剪的重要性不容小觑。图像裁剪从图像中提取子图像。这使得可以专注于自然场景或实验室样本里被认为有趣的、相关的、值得仔细观察的那部分。像素强度是用于镶嵌图像的生成点(网点)的另一个来源,可以产生从不同视角揭示图像几何和图像目标的图像 网格。
  例3.1
  在附录A.3节中列表A.22的Matlab程序被用来执行如下操作:
  (1)裁剪一幅RGB图像以获得一幅子图像。例如,对图3.2中的大图像进行裁剪可得到图3.3中的微小图像结果。
  (2)生成一个3-D网格,展示组合的RGB像素值。对裁剪图像得到的结果如图3.1 所示。
  (3)生成一个3-D网格,其轮廓为红色通道值。对裁剪图像中像素的红色通道值得到的结果如图3.4(a)所示。
  (4)生成一个3-D网格,其轮廓为绿色通道值。对裁剪图像中像素的绿色通道值所得到的结果如图3.5所示。彩色图像中的绿色通道值通常倾向于在小值和值之间具有数量的变化。因此,绿色通道是在图像的沃罗诺伊镶嵌中使用的生成点(网点)的选择中寻找不均匀性的好地方。为了看到这一点,考虑3-D网格与它们的轮廓之间的差异,首先从图3.5里绿色通道的3-D网格开始,并与图3.4(a)中的红色通道值和图3.4(b)中的蓝色通道值进行比较。
