如何从二进制图像中获取值1或0？ [英] How to get values 1 or 0 from binary images?

问题描述

这是我的代码

That is my code

Image<Gray, Byte> image = new Image<Gray, byte>(Openfile.FileName);
pictureBox1.Image = image.ToBitmap();
image1 = image1.ThresholdBinary(new Gray(50), new Gray(255));

我打开我的图片桌面并将其转换为灰度，然后二进制。我想从二进制图像中获取值1或0，以便存储在矩阵中。我怎样才能做到这一点？？我正在使用emgucv。

I open an image from my desktop and convert it to grayscale and then binary. I want to get either the values 1 or 0 from binary images in order to storage in matrix. How can I do that?? I am using emgucv.

推荐答案

记住黑白图像的值为0和255.所以如果你想要0和1，那么：

Remember a black and white image has values 0 and 255. So if you want 0 and 1 then either:

image = image.ThresholdBinary(new Gray(50), new Gray(255));

 for (int v = 0; v < image.Height; v++)
 {
     for (int u = 0; u < image.Width; u++)
     {
         int a = image.Data[v, u, 0] & 1; //Get Pixel
    }
 }

OR

image = image.ThresholdBinary(new Gray(50), new Gray(1));

for (int v = 0; v < image.Height; v++)
{
    for (int u = 0; u < image.Width; u++)
    {
        int a = image.Data[v, u, 0]; //Get Pixel
    }
}

在这个例子中，我们使用图像的Data属性。 http://www.emgu.com/wiki/index.php/Working_with_Images [ ^ ]
