It means that the foreground objects look different than the background, especially meaning their intensity levels. I'm not sure why you're confused. Why is that not obvious? Am I overlooking some nuance that you had in mind?

@ Image Analyst. Thanks for your answer. I think In was a bit confused since I'm kind of new to digital image processing.
