问题:

How, can I have a buffer or array of images "Mat" with OpenCV?

I mean: having a set of images, want to pick up and put in an array like

How can I do this? It's like C++ normal array style?

 Mat images[2];

    images[0] = imread(...);
    images[1] = imread(..);

Thanks in advance.

Just declare a array of cvMat object as-

Mat image_array[10];      // array of 10 images

Now read the images into it according to index of the array

image_array[0]=imread("/home/me/Pictures/img1.png",1);
image_array[1]=imread("/home/me/Pictures/img2.png",1);
......
......
image_array[9]=imread("/home/me/Pictures/img9.png",1);

I had to implement something similar and I didn't need to view the images all I wanted was to extract some data from them but I'm going to add the imread anyway. Here is the code:

Mat mat[10];enter code here
char c[n]; //n is the size of chars in the directory of images

for(int i=1;i<=10;i++)
{
 sprintf(c,"/directory to images/%d.jpg",i);
 mat[i] = imread(c);
 imshow("mat",mat[i]);
 waitKey(0);
}

this is going to display the first image in the array and you will have to press any key to go to the next one. Hope this helps
