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...

Rabies positive cells were assigned to one of the two components (i.e., superficial and deep layers) created by the clustering algorithm. Data is presented as the proportion of all rabies labelled cells in each layer. As an internal control data for cholera toxin labelling is also presented ...
We propose a structural similarity (SSIM)-motivated two-pass variable bit rate control algorithm for High Efficiency Video Coding. Given a bit rate budget, the available bits are optimally allocated at group of pictures (GoP), frame, and coding unit (CU) levels by hierarchically constructing a ...
