What kinds of statistical analyses and ML methods are good for comparing images? career advice?

I am just a beginner-level programmer in Python and MATLAB, and I have been looking at tutorials for Keras. Eventually, I want to make a project for my programming portfolio. Can you please share some ideas about how to get started with this project as well as any career advice about getting started with data science and machine learning?

Here’s an example of a project idea I want to work towards: Comparing images of the rainforest to simulate deforestation trends with statistics and percolation theory.
