Showing two images side by side is an easy way to draw comparisons between two similar images. By doing this, you can see at a glance the similarities or differences between them. Matlab provides many easy methods to accomplish this task. This guide will provide a step-by-step guide to show two images side by side in Matlab.

Step 1: Importing the Images

The first step is to import both images into Matlab. This can be done through either the “Import” command, or by using the “guidata()” object. To import the images with the “Import” command, enter “import” in the Matlab Command Window and then browse to the location of the images. To import with the “guidata” object, use the following code:

im1 = imread(‘image1.png’);
im2 = imread(‘image2.png’);

Step 2: Resizing the Images

Once you’ve imported the images, the next step will be to resize them. To do this, Matlab provides the “imresize()” function. This function takes two arguments: the image to resize and the desired new size of the image. You can either enter the new image size as a fraction of its original size, or as absolute pixel sizes (i.e. width x height). For example, to resize the images to half their original size, use the following code:

im1 = imresize(im1, 0.5);
im2 = imresize(im2, 0.5);

Step 3: Showing the Images Side by Side

Now that you’ve imported and resized both images, the final step is to show them side by side. To do this, Matlab provides the “subplots()” function. This function creates two subplots (which are essentially two separate images) and displays them side by side. To use this function, use the following code:

subplot(1,2,1);
imshow(im1);
subplot(1,2,2);
imshow(im2);

This code will display the two images side by side.

Summary

Showing two images side by side in Matlab is a simple task that can be accomplished with the “Import” command or the “guidata()” object for image import, the “imresize()” function for resizing, and the “subplots()” function for showing two images side by side. This guide provides a step-by-step guide on how to show two images side by side in Matlab.

FAQ

What is the “subplots()” function in Matlab?

The “subplots()” function in Matlab is a function that creates two subplots (which are essentially two separate images) and displays them side by side.

How do I import images into Matlab?

You can import images into Matlab by either using the “Import” command or the “guidata()” object. To import the images with the “Import” command, enter “import” in the Matlab Command Window and then browse to the location of the images. To import with the “guidata” object, use the following code:

What is the “imresize()” function?

The “imresize()” function is a function in Matlab that resizes an image. It takes two arguments: the image to resize and the desired new size of the image. You can either enter the new image size as a fraction of its original size, or as absolute pixel sizes (i.e. width x height).

What are the advantages of showing two images side by side?

Showing two images side by side is an easy way to draw comparisons between two similar images. By doing this, you can see at a glance the similarities or differences between them. This can be a useful tool for visualizing differences between data sets.

What is markdown format?

Markdown is a markup language used to format text. It is popular among developers because it is easy to write and read. In markdown, text is formatted using symbols such as asterisks and hashtags, making it much easier to read than HTML. It can also be used to create links, images, and lists.
