What math do they use and how does it work?
I have 2 quetions what math do they use to put a hidden picture or information in a picture like a Jpg ? And how does this work?
And what math or software do they use to make picture bigger or make it clear.
That say a security camera like a robbery and they use cheap camera and low quality .What math would they use to make it bigger and clear .
Low quality and small picture.

I thought the video enhancing department of the police station use adobe photoshop ? Some one was saying there is no limit to video enhancing still image or moving image it is just more math.
How does this work and how long does this take? Can person at home with no training or little training do it?

Putting hidden information in pictures = stegography

Enhancing craptacular images to something decent = Hollywood BS.
There’s software that will make an effort and produce some tiny improvements, but the Enhance Button (TM) button used in movies and police shows is about as real as the replicator in StarTrek.
Your link doesn’t work, by the way.

Okay, I had a look at the link. The guy’s face is about 2 pixels. Seriously. He could be anyone. He could be a woman. He could be a woman in a Klingon suit.
You can run those 2 pixels through sophisticated software all week but you’ll never get a recognizable face. The information just isn’t there to begin with.
