如何将图像转换为黑白(0或1)? [英] How I can transform image to black and white (0 or 1) ?
问题描述
我使用visual studio 2010并打开CV库,用C语言
我的问题是如何将图像pgm转换为pbm例如放入like * file并仅在二进制0中读取图像或1?

我尝试过:
将图像转换为灰度
#includeopencv2 / core / core.hpp
#includeopencv2 / highgui / highgui.hpp
#includeopencv2 / imgproc / imgproc.hpp
#includeiostream
使用namespace cv;
using namespace std;
int main()
{
Mat图像;
image = imread(lena.jpg,CV_LOAD_IMAGE_COLOR);
if(!image.data)
{
cout<< 无法打开或找到图像<< std :: endl;
返回-1;
}
//创建一个新矩阵来保存灰色图像
Mat灰色;
//将RGB图像转换为灰色
cvtColor(图像,灰色) ,CV_BGR2GRAY);
namedWindow(显示窗口,CV_WINDOW_AUTOSIZE);
imshow(显示窗口,图片);
namedWindow(结果窗口,CV_WINDOW_AUTOSIZE);
imshow(结果窗口,灰色);
waitKey(0);
返回0;
}
I using visual studio 2010 and open CV library , in C language
my question is how I ca transform image pgm to pbm for example after put like *file and read the image only in binary 0 or 1 ?

What I have tried:
this to convert image to greyscale
#include "opencv2/core/core.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include "iostream"
using namespace cv;
using namespace std;
int main( )
{
Mat image;
image = imread("lena.jpg", CV_LOAD_IMAGE_COLOR);
if(! image.data )
{
cout << "Could not open or find the image" << std::endl ;
return -1;
}
// Create a new matrix to hold the gray image
Mat gray;
// convert RGB image to gray
cvtColor(image, gray, CV_BGR2GRAY);
namedWindow( "Display window", CV_WINDOW_AUTOSIZE );
imshow( "Display window", image );
namedWindow( "Result window", CV_WINDOW_AUTOSIZE );
imshow( "Result window", gray );
waitKey(0);
return 0;
}
