MATLAB: 256×256 medical image gives me 256x256x3

image fusionmedical imagewavelet

I need a 256×256 pixels image to use it in my project. I downloaded images from the internet, but when I read the image, it stored in a 256x256x3 variable (color image format PET images). the NSCT fusion algorthms gives me errors (dimension of matrices)

What is the reason for this and what can I do? here is the code to read the image

img1=imread('pet.jpg');

img2=imread('ct.jpg');

You can convert it into gray image using rgb2gray.

I1 = rgb2gray(I) ;   % where I is RGB image

MATLAB: Convert 16X16 to 256X256

B = zeros(256,256);
B(1:size(A,1),1:size(A,2)) = A;  %upper left
B(end-size(A,1)+1:end, 1:size(A,2)) = A; %lower left

With obvious generalizations to upper right and lower right

c = floor((size(B)-size(A))/2);
B(c(1)+1:c(1)+size(A,1), c(2)+1:c(2)+size(A,2)) = A;  %center

The centering algorithm biases towards the upper left if the sizes are not both even or not both odd.
