Circumvent the 'array exceeds maximum array size preference' error

I'm doing a project on image stitching for a course. The end result is to show a panorama where all images are stitched. If there are a lot of images, sometimes i get the 'array exceeds maximum array size preference' error when I create the black canvas to overlay all my transformed images. Is there a way to circumvent this?

For example, by instead of using RGB tensors, using a different type of image representation that is less memory-consuming, like a simple matrix. How would I go about to do it? Any other ideas?

Rescaling the images and panoramas would work, but I need to provide coordinates of specific points in the final paroama for evaluation and this would be altered by rescaling.

Thank you in advance.

You can have a look at imageDatastore. It can be useful for managing a collection of image files, where each individual file fits into memory but the entire collection of images does not necessarily fit.

You can also have a look at the variable size preference:

You can refer to the following link for resolving "out of memory" errors:
