An image is represented by a 2-D array of integers, each integer representing the pixel value of the image (from 0 to 65535). Given a coordinate (sr, sc) representing the starting pixel (row and column) of the flood fill, and a pixel value newColor,…

An  image is represented by a 2-D array of integers,each integers,each integer respresenting the staring pixel value of the image (from 0 to 65535) Given a coordinate (sr,sc)representing the starting pixel (row and column) of the flood fill ,and a pi…

泛洪填充算法(Flood Fill Algorithm) 泛洪填充算法又称洪水填充算法是在很多图形绘制软件中常用的填充算法,最熟悉不过就是 windows paint的油漆桶功能.算法的原理很简单,就是从一个点开始附近像素点,填充成新 的颜色,直到封闭区域内的所有像素点都被填充新颜色为止.泛红填充实现最常见有四邻域 像素填充法,八邻域像素填充法,基于扫描线的像素填充方法.根据实现又可以分为递归与 非递归(基于栈). 在介绍算法的三种实现方式之前,首先来看一下测试该算法的UI实现.基本思路是选择一…
