Hello there. i am a senior student in electrical 
engineering. My term Project is about to identify source 
camera. While identifing, i should use image noise for 
comparing all images that i took before. What i am asking 
is how i can find or obtain the noise of any image. i have 
looked at all topics and workouts about this subject. All 
of them are about denoising or removing the noise. it is 
useless for me at this time. Anyway, if you have any idea 
or if you did any Project like this before can you tell me 
how i can obtain the noise of an image in MATLAB. Thanks.
