I started with background subtraction between a static background and another image with a foreground object(hand) that were captured from webcam. I couldn't get good results. I have attached the code i used and images below.

You do not appear to be accounting for illumination differences. Possibly that would help.

You can avoid the loop by saying
binaryImage = Out > 3; % Or some number that works.
Then use bwareaopen() or bwareafilt() to get rid of small blobs.

Can you make it easier to help you? Can you attach your separate images?

See my attached code.
If you want a smoother background, like to not have the movement of the drapes shadow be connected to the arm, you can use activecontour(). I've also attached a demo for that so you should be off to a good start.
Note: This may not be the best approach - the foreground detector in the Computer Vision System Toolbox may work better.

Sorry, I can't. Besides, I don't even have the Fuzzy Logic Toolbox.

You can use vision.ForegroundDetector in the Computer Vision System Toolbox.
