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找出来,并填充上新的

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 ...
Also provided a coordinate(sr, sc) representing the starting pixel (row and column) and a new color value newColor. Your task is to perform a flood fill starting from the pixel (sr, sc), changing its color to newColor and the color of all the connected pixels that have the same ...

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 ...
