AI tackles Photoshop fakes
Adobe is leaning on artificial intelligence to detect Photoshop image manipulation. The company says AI is able to identify the kind of manipulation used and highlight the area of the photograph that has been altered.
One technique uses an RGB stream – changes to red, green and blue colour values of pixels – to detect tampering. The second technique uses a noise stream filter examining random variation of colour and brightness that may be a by-product of software manipulation.
Future develop could explore other artifacts of manipulation, such as differences in illumination throughout a photograph, or compression caused by repeated saving of digital files.
