two pass 连通区域算法two pass连通区域算法 两遍算法(Two-pass algorithm)是图像处理中一种用来查找和标记图像中连通区域(或联通分量、区域)的方法。这种算法首次被提出是在20世纪60年代,如今已成为图像处理中常用的一种方法。这种算法相对简单而且高效,因此在实际应用中被广泛使用。在本文中,我们将详细介绍两遍算法...

在FirstPass时,取周围点的标记最小值,map[标记]=min,这样就构成了map数组,然后根据map数据进行第二次标记。 实现 intImageAlgorithm::TwoPassConnetedDomin(Mat image){ Mat imageFlag; imageFlag.create(image.rows, image.cols, CV_16UC1);for(intk =0; k < image.rows; ++k) {for(inti =0; i <...
连接组件标记算法(connected component labeling algorithm)是图像分析中最常用的算法之一,算法的实质是扫描一幅图像的每个像素,对于像素值相同的分为相同的组(group),最终得到图像中所有的像素连通组件。扫描的方式可以是从上到下,从左到右,对于一幅有N个像素的图像来说,最大连通组件个数为N/2。扫描是基于每个像素...
The algorithm is effective in terms of combating some of the cone beam artifacts. However, when objects with high density and non-uniform distribution are placed off the center plane (the fan beam plane), severe shading artifact will result. In the paper, we propose a two- pass cone beam ...

In image rotation, a two-pass algorithm has many advantages over a one-pass algorithm in high speed computation. The reported two-pass algorithm gives a serious performance degradation in high frequency area at large rotation angles (30 degrees to 45 degrees). This paper presents a new two-pas...
