Given the amount of information analysis we're seeing applied to things like extracting heartbeats out of videos, I think we're safe in saying that any colorization or modification of a photo will be detectable, or at least have a probability assignment to the chances the photo has been manipulated.
- StavrosK 11y agoHow would you even begin to do that?
- kordless 11y agoIt starts with the pixels. :) Purely speculation: it would involve modeling the 3D environment in the photo and then changing colors until you get a similar distribution of light (say shadow areas) in each iteration which has some sort of matched probability distribution as the original photo. With a nearly limitless amount of compute, you can do anything "close enough", which to the point of the article, is a refutation of the claim that people are "rewriting history". What is "history"? Why is a precise view of it so important?
