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...

System and a two-pass algorithm for determining the optimum access path for multi-table SQL queriesAn apparatus, article of manufacture and computer-based method is provided for determining the optimum join sequence for processing a query having a plurality of tables from a relational database ...
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 ...
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...

These two transformations are computed using a least square fit algorithm. Resampling with bilinear or cubic convolution interpolation is also separable into the two-pass technique. This algorithm is suitable for hardware implementation of current image processing systems. 展开 ...
In this paper, we propose a novel two-pass rate control algorithm to achieve constant quality for H.264/AVC high definition video coding. With the first-pass collected rate and distortion information and the built model of scene complexity, the encoder can determine the expected distortion which...
