How can I get this to print 1 row of my original 3 images on top of 1 row of my three altered images?

• Read the three images into your script (the images have to be saved in your working directory so your code can find them)
• Resize the images to be the same size using imresize
• Duplicate both of the images and change the RGB values in a way that you like.
• Concatenate the original and recolored images however you would like - 6 images total
• Display the collaged image in a figure and add a title

Here is my code and I don't know what is wrong with it. Please help me! Thank you in advance.

% Read three images into script

image1 = imread('Cross_Image.jpg');

image2 = imread('Monkey_Image.jpg');

image3 = imread('Nature_Image.jpg');

% Resize three images to be same size

image1 = imresize(image1, [213,413]);

image2 = imresize(image2, [213,413]);

image3 = imresize(image3, [213,413]);

% imshow(image1)

% imshow(image2)

% imshow(image3)

% Duplicate three images

image11 = imread('Cross_Image.jpg');

image22 = imread('Monkey_Image.jpg');

image33 = imread('Nature_Image.jpg');

% Resize three altered images

image11 = imresize(image11,[213,413]);

image22 = imresize(image22,[213,413]);

image33 = imresize(image33,[213,413]);

% Alter three images

alteredimage1 = image11(:,:,3) + 15;

alteredimage2 = image22(:,:,2) + 53;

alteredimage3 = image33(:,:,2) + 10;

% Show three images

figure;

imshow([image1 image2 image3]);imshow([alteredimage1, alteredimage2, alteredimage3])

Try putting the altered images in the row below the originals.

imshow([image1 image2 image3; alteredimage1, alteredimage2, alteredimage3], [])

[Me]

I still get a blank figure and an error message that says:

Error using vertcat

Dimensions of arrays being concatenated are not consistent.

[Me]

If I take out the altered image portion it works, but I need to change the images, so they do not look like the original. How can I still change the images and get them to be the same dimensions? Right now alteredimage1, 2, and 3 are only 213 x 413 instead of 213 x 413 x 3

[Image Analyst]

Try imtile or montage

[Me]

I tried both of those and it still gives me the same error. I am not sure why the dimensions are only 213 x 413 instead of 213 x 413 x 3. Is there another way I can alter the images, so it will not change the size?

[Me]

If I comment out the altered image1, 2, and 3 and just leave the images resized and code:

figure;

imshow([image1 image2 image3;image11,image22,image33])

title('Image Collage')

the code works. If I try to alter it, like I was asked, it no longer works because the dimensions are off.

When you do this

% Alter three images
alteredimage1 = image11(:,:,3) + 15;
alteredimage2 = image22(:,:,2) + 53;
alteredimage3 = image33(:,:,2) + 10;

You're taking only one color channel. If you want to alter only one color channel you have to initialize altered images.

% Alter three images
alteredimage1 = image11;
alteredimage1(:,:,3) = image11(:,:,3) + 15;
alteredimage2 = image22;
alteredimage2(:,:,2)  = image22(:,:,2) + 53;
alteredimage3 = image33;
alteredimage3(:,:,2) = image33(:,:,2) + 10;

Oooh okay! Thank you so much! I don't know why I didn't think of that. I really appreciate your help!
