Academic fair use and using publication images in your thesis

In the introductory chapter of my thesis, I've been surveying the previous work in my field. As part of this, I've used images from some of those publications and included them as Figures in my own thesis.

Occasionally, I have slightly edited them - for instance, changing the labelling.

I usually only use one image from each paper.

My understanding is that this falls under academic fair use, and I do not need permission from any of the publishers to re-use these images in my thesis.

Am I correct?
