How to align two images from different sources?

Hi!
I am working on a project to fuse two images, RGB + Infrared (1 Channel). I noticed the images from RGB source has a slightly wider angle than IR source. Both image souces have different resolution as well. RGB 1800x1600pixels, whereas IR source 640x512 pixels. I have tried to manually crop and then feed new image into fusion algorithm, but I would not consider my croping to be as good. Is there an optimal way to align two images, so that they can be fed into an algorithm?

You may use imfuse function. Link to documentation: https://www.mathworks.com/help/images/ref/imfuse.html
First resize the RGB image and then apply imfuse
a = imread('RGBImage.jpg');
a = imresize(a,[512,640]);
b = imread('IRImage.jpg');
c = imfuse(a,b);
imshow(c)

Hi Sai!
Thanks a lot for getting back to me! I have attempted above fusion, but it doesn't look very good as you can see shadows. Maybe if I can crop the images properly, maybe it will have less shadow. I am also planning to run the fusion through a different algorithm. My goal is to reduce shadows, or have no shadows at all.
