图像处理之漫水填充算法(flood fill algorithm) 基本思想 漫水填充算法,顾名思义就像洪水漫过一样,把一块连通的区域填满,当然水要能漫过需要满足一定的条件,可以理解为满足条件的地方就是低洼的地方,水才能流过去。在图像处理中就是给定一个种子点作为起始点,向附近相邻的像素点扩散,把颜色相同或者相近的所有点都...
算法类源代码如下: package com.gloomyfish.paint.fill;import java.awt.image.BufferedImage;import com.gloomyfish.filter.study.AbstractBufferedImageOp;public class FloodFillAlgorithm extends AbstractBufferedImageOp {private BufferedImage inputImage;private int[] inPixels;private int width;private int height;// s...
The flood fill algorithm takes three parameters: a start node, a target color, and a replacement color. The algorithm looks for all nodes in the array which are connected to the start node by a path of the target color, and changes them to the replacement color. There are many ways in ...

Flood fill algorithm can be simply modeled as graph traversal problem, representing the given area as a matrix and considering every cell of that matrix as a vertex that is connected to points above it, below it, to right of it, and to left of it and in case of 8-connections, to the...

Path planning of a mobile robot poses different problems, which are of great importance nowadays, in that robotics not only offers industrial solutions, as it is the case of the domestic robots. A solution to the path planning is the algorithm Flood Fill, which is the basis of development ...

1) Flood Fill algorithm 洪水算法 1. By looking up this table, the points whose phase needs to be unwrapped were put into a virtual queue, which is equal to the ordered queue inFlood Fill algorithm. 在相位展开过程中,通过查表将相位待展开的点放到一个虚拟队列(等同于洪水算法中的有序队列)中...
