Above: “Image Restoration” taken from Part I: Fundamentals and Local Models of the Tutorial on Modeling Natural Image Statistics for Computer Vision by Siwei Lyu and Stefan Roth.
The Times Union recently had a write up on Assistant Professor Siwei Lyu from University at Albany. An excerpt from the article…
Computers allow digital photographs to be easily manipulated in such a way that the human eye cannot detect the forgery. But University at Albany Assistant Professor Siwei Lyu is training computers to do the important work that mere mortals cannot.
These days, it’s not hard to remake reality on your home computer, with Photoshop programs and built-in software on cameras that allows for immediate manipulation.
Lyu has developed a system that turns digital photos into a mathematical computer language that make it easier to investigate “photo-chopping” and determine the components of a natural image.
“We’re just playing detectives,” he said. “It’s easy to fake images.”
If you (like myself) are a true nerd about this stuff and want to read more on the work Lyu is doing, you can find links to his research here.
