I need a 256x256 pixel 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 algorithms gives (dimension of matrices error)
What can I do? here is the code to read the image
img1=imread('pet.jpg');
img2=imread('ct.jpg');

thank you very much, but i need the final image in my algorithm to be colormap not grayscale, what can I do?

The preprocessing stage, in this article, may help you to understand this problem.
Dear Majid Nullo
The color image has three planes (Red, Green, and Blue), so the image is said to be a 3D array.
You can convert it to gray scale or 1D before the processing. Finally, you can return it to the original format using the conversion function.
Try to download the image as gray scale image from data set site as :

Hello Majid Nullo
In image processing, there are various kinds of initial issues for beginners.
To make the basic understanding one can follow some user guides that provide a base to work on smoothly.
some examples are given below:

They are three-channel. You could convert them grayscale with ImageJ software.
With Matlab, we have :
