With the fast proliferation of digital cameras and other image acquisition devices due to the advancement in digital photography technology, photos from the public may have good news values for making journalist reports. However, one big challenge is how to authenticate the visual contents from the public, which may come from unreliable sources. Can we trust what we see in a photo?
In this talk, Prof. Alex Kot will show different types of manipulated images videos and deepfake. A large variety of forensics works have been proposed to detect these manipulated images and videos based on different types of tell-tale signs. Several techniques in detecting such manipulations will be introduced. These techniques help expose common image forgeries, especially those easy-to-make forgeries, which can be hardly seen directly by human eyes.
