第三章 灰度变换与空间滤波 3.1 背景知识 3.1.1 灰度变换和空间滤波基础 本章节所讨论的图像处理技术都是在空间域进行的.可以表示为下式: $$g(x, y) = T[f(x,y)]$$ 其中$f(x,y)$是输入的图像,$g(x,y)$是处理后的图像,$T$是在点$(x,y)$的邻域上定义的关于$f$的一种算子. 对于图像处理由以下几步组成:邻域原点从一个像素向另一个像素移动,对邻域中的像素应用算子T,并在该位置产生输出.对于边界情况,则根据算子的相关定义处理. 这样的过程称之为空间滤波…

此主要讨论图像处理与分析.虽然计算机视觉部分的有些内容比如特 征提取等也可以归结到图像分析中来,但鉴于它们与计算机视觉的紧密联系,以 及它们的出处,没有把它们纳入到图像处理与分析中来.同样,这里面也有一些 也可以划归到计算机视觉中去.这都不重要,只要知道有这么个方法,能为自己 所用,或者从中得到灵感,这就够了. 注意:Registration可翻译为“配准”或“匹配”,一般是图像配准,特征匹配(特征点匹配). 15. Image Registration图像配准最早的应用在医学图像上,在图像融合…
