寻找连通线,参考八后算法递归,可用于验证码去除连续干扰线

#include <iostream>
using namespace std;

#define M 5
#define N 4
int a[M][N] = {0,1,0,1,0,1,1,0,1,1,0,0,1,0,1,0,1,0,1,0};
int b[M] = {};
void genLine(int n)
{
	if (n == M)
	{
		for (int i = 0; i < M; i++)
		{
			cout<<b[i]<<' ';
		}
		cout<<endl;
	}
	if (n==0)
	{
		for (int j = 0; j < N; j++)
		{
			if (a[0][j] == 1)
			{
				b[0] = j;
				genLine(n+1);
			}
		}
	}
	if (n > 0)
	{
		int p = b[n-1];
		if (b[n-1] > 0 && a[n][b[n-1]-1] == 1){
			b[n] = b[n-1]-1;
			genLine(n+1);
		}
		b[n-1] = p;
		if (a[n][b[n-1]] == 1){
			b[n] = b[n-1];
			genLine(n+1);
		}
		b[n-1] = p;
		if (b[n-1] < N && a[n][b[n-1]+1] == 1){
			b[n] = b[n-1]+1;
			genLine(n+1);
		}
	}
}

int main (int argc,char** args) 
{
	for (int i = 0; i < 5; i++)
	{
		for (int j = 0; j < 4; j++)
		{
			cout<<a[i][j]<<" ";
		}
		cout<<endl;
	}
	cout<<"----------------------------------"<<endl;
	genLine(0);
	
  return 0;
}

0 1 0 1 0 1 1 0 1 1 0 0 1 0 1 0 1 0 1 0 ---------------------------------- 1 1 0 0 0     

1 1 1 0 0  表示红色部分连通路径,第一行1列,第二行1列,第三行1列,第四行0列,第五行0列 1 1 1 2 2 1 2 1 0 0 1 2 1 2 2 3 2 1 0 0 3 2 1 2 2

这个算法加入域值控制扩展一下就可以识别验证码中的连续干扰线

原始图片

算法找到的干扰线，为了显示，显示成红色了。当然我们很容易把这条红色的干扰线删掉，然后用一下腐蚀算法，图片的预处理效果就比较好了。
