MATLAB: Extracting background/foreground of an image

Question

Hey Guys, I am currently starting to get into matlab and want to experiment with some images. So basiccaly I load two images (the same, but different angle) and I want to extract their background or foreground. So basically if I detect a human in the foreground, it should „extract“ him. (The goal in the end, is to place the extracted foreground on a different background) But how do I find this human in the background. Should I do some correspondence calculation with harris detector or something like that? Should I transform the images into grayscale? What is the best way to calculate this mask to extract the features of an foreground/background. Is there a way without using some toolboxes? If not, what kind of toolboxes would help. Thank you very much Guys !!

If your background is static, then you can get one with no humans and subtract it from the test image and look for differences.
