How do i stitch or merge an image together

I would like to merge/stitch 6 image together but, there is a missing part inside (which is meant to be).

The overal image will form a final image (with a hole in a middle (missing pieces).

How do i stitch the images as per the image above? Thank you

Hi,

I am assuming that-

1. All your individual images A to F are RGB images
2. The values in the missing part can be NaN in the final merged/stitched image.

Sample code to get the final merged/stitched image is attached below-

% Creating test images A to F with different colours
A = ones(5,12,3); % creating image A
A(:,:,1) = 0;     % setting color of A = cyan
B = ones(4,6,3);  % creating image B
B(:,:,2) = 0;     % setting color of B = magenta
C = ones(4,6,3);  % creating image C
C(:,:,3) = 0;     % setting color of C = yellow
D = ones(7,4,3);  % creating image D
D(:,:,[1 2]) = 0; % setting color of D = blue
E = ones(7,4,3);  % creating image E
E(:,:,[2 3]) = 0; % setting color of E = red
F = ones(3,12,3); % creating image F
F(:,:,[1 3]) = 0; % setting color of F = green

% Merging/stitching the images
w = size(A,2);
wD = size(D,2);
wE = size(E,2);
hDE = size(D,1);
finalImage = [A; [B C]; [D NaN(hDE,w-wD-wE,3) E]; F];
imagesc(finalImage);

For more information, please refer to the documentation on-

1. Creating, Concatenating and Expanding Matrices
2. Create array of all NaN values
3. Display image with scaled colors
