AI identifies hidden cameras in everyday objects.

Researchers at MIT and Adobe Research have developed a machine-learning approach that can identify all pixels in an image representing a given material, which is shown in a pixel selected by the user. The method is accurate even when objects have varying shapes and sizes, and the machine-learning model they developed isn’t tricked by shadows or lighting conditions that can make the same material appear different. The approach can also be used for videos; once the user identifies a pixel in the first frame, the model can identify objects made from the same material throughout the rest of the video.
