‘Mirage’ Helps You Detect Edited Photos Using Machine Learning

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.

Private Messenger ‘Signal’ Now Automatically Blurs Faces

Private messenger app Signal added a feature that lets it automatically blur faces in your images.

Thousands of people are protesting against police brutality and to support the Black Lives Matters cause. If you are a part of the protests, you might post photos of the demonstration around you on social media or send them to your friends — and that’s not entirely safe, because it could help identify people there and put them in danger.

A great feature. I’ve been trying to create a shortcut that can obfuscate faces.
