Accessing all the pixels of an Image

To access full pixel value of an image,
We can use :
    Vec3b imagepixel = image.at(x,y);
in for loop to change the value of the co-ordinates (x,y) to cover each row and column.

         for (int j = 0; j < image.cols; j++) 
           { 
            Vec3b imagepixel = image.at<Vec3b>(i, j);
            cout<<imagepixel ;   //Displaying the pixel value  of the whole image

What will happen if we put ,
     cout<<image;
Does it prints the whole pixel array of an image?*

Notice the difference in output of both the pixel arrays
