# 1. Java种子填充算法概述 种子填充算法是一种用于填充封闭区域的算法,广泛应用于图像处理和图形学中。它通过递归或迭代的方式,从一个种子点开始,逐像素填充封闭区域内的所有像素。 种子填充算法有两种主要类型:扫描线填充算法和边界填充算法。扫描线填充算法沿水平扫描线进行填充,而边界填充算法沿边界进行填充。这两种算法各有优缺点,具体选择取决于具体应用场景。 # 2. 替代算法理论基础 ### 2.1 扫描线填充算法 #### 2.1.1 扫描线填充算法原理 扫描线填充算法是一种基于逐行扫描图像的填充算法。其基本原理是: 1. **确定填充区域的边界:**首先,算法确定需要填充的区域的边界,即该区域的顶点和边。 2. **按扫描线扫描:**从图像的顶部开始,算法逐行扫描图像,直到到达图像的底部。 3. **计算填充像素:**对于每一行,算法计算出该行与填充区域相交的部分,并填充这些像素。 #### 2.1.2 扫描线填充算法实现 扫描线填充算法的实现主要涉及以下步骤: 1. **初始化:**设置一个数据结构来存储填充区域的边界,例如一个边缘表。 2. **扫描循环:**对于图像中的每一行,执行以下步骤: - 计算该行与填充区域的相交部分。 - 填充相交部分的像素。 3. **重复扫描:**重复步骤 2,直到扫描完图像的每一行。 ### 2.2 边界填充算法 #### 2.2.1 边界填充算法原理 边界填充算法是一种基于递归的填充算法。其基本原理是: 1. **确定填充区域的边界:**首先,算法确定需要填充的区域的边界,即该区域的顶点和边。 2. **递归填充:**从填充区域的任意一个边界点开始,算法递归地填充与该点相邻的未填充像素。 3. **终止条件:**当算法遇到填充区域的边界或已经填充过的像素时,递归终止。 #### 2.2.2 边界填充算法实现 边界填充算法的实现主要涉及以下步骤: 1. **初始化:**设置一个数据结构来存储填充区域的边界,
