How to remove the background of the person image?

I have two images, one contains the person and one is its background. The two photos were taken twice, so there was a slight deviation.

I want to remove the background of the photo that contains people, I mean, remove everything from the background photo.

Do you have any way to do this? Please guide me, because I am a beginner with Matlab. Thank you.

I suppose you can do it, using K-means clustering technique. I dont have Matlab 2018b, hence unabled to test it.

Thanks for your help. I have read the article and found it useful, I will try it now. I will use K-menas clustering technique on the background image to find objects and then delete those objects on the image containing people. so true?

K-means cetegories the input image to k regions only, you can extract the regions, those are required.

Good Luck!
