2:1 zoom in of pictures

Hello everyone.

I want to reduce 4 images of 256 x 256 pixels in a ratio of 2:1.

After reducing it, I want to combine it side by side and one under the other so that it is a 2x2 matrix and make it a single picture.

I want to calculate the mean and standard deviation of this image I have obtained.

How can i do it? Is anyone help me?

Best regards.

% Read the four standard images

image1 = imread('image1.jpg');

image2 = imread('image2.jpg');

image3 = imread('image3.jpg');

image4 = imread('image4.jpg');

% Resize the images to the desired size of 256x256 pixels

image1_resized = imresize(image1, [256 256]);

image2_resized = imresize(image2, [256 256]);

image3_resized = imresize(image3, [256 256]);

image4_resized = imresize(image4, [256 256]);

% Create a blank canvas for the combined image

combined_image = uint8(zeros(256, 512, 3));

% Place the resized images side by side in the combined image

combined_image(:, 1:256, :) = image1_resized;

combined_image(:, 257:512, :) = image2_resized;

combined_image(:, 513:768, :) = image3_resized;

combined_image(:, 769:1024, :) = image4_resized;

% Display the combined image

imshow(combined_image);
