I know this should be simple but I really cannot figure it out. How do I take two images and then have them display overlap each other at the central point (I have included a figure below)? These pictures are of different sizes. And I would like to do this without "hard-coding"
I have A = imread('A.png'); A = imread('B.png'); imshow (A) hold on; imshow (B)
But after this I have no idea how to center these :(

Probably the easiest way is to copy and past the box at the proper location. You can easily find out the coordinates using the size function
[rows1, columns1, numberOfColorChannels1] = size(image1);
[rows2, columns2, numberOfColorChannels2] = size(image2);
col3 = int32(columns2/2 - columns1/2);
col4 = col3 + columns1 - 1;
row3 = int32(rows2/2 - rows1/2);
row4 = row3 + rows1 - 1;
Then paste in to each color channel. See my attached demo.

Well go ahead and mark it "Accepted" then. Thanks. Hard coding woul dbe where you specify the actual numerical coordinates, like
image2(200:300, 500:550) = image1;
It would always put it at those column and row locations and not adapt to the size of image1.
