Mirage is a cool app I discovered today that uses machine learning to detect edited photos. Not only that, it can also undo the editing. However, it requires a face to be present in the photo, so it won’t work on any image. It’s based on this research paper [PDF]:
We present a method for detecting one very popular Photoshop manipulation – image warping applied to human faces – using a model trained entirely using fake images that were automatically generated by scripting Photoshop itself. We show that our model outperforms humans at the task of recognizing manipulated images, can pre- dict the specific location of edits, and in some cases can be used to “undo” a manipulation to reconstruct the original, unedited image.
App Store: Mirage – US$2.99
