# Computational Mirror Systems MIT Researchers Used Shadow Footage to Detect Objects Around Corners By Daniel Johnson | Published 2019-12-10 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/shadow-footage References: [engadget](https://www.engadget.com/2019/12/06/mit-csail-algorithm-recreates-video/) & [csail.mit.edu](https://www.csail.mit.edu/news/imaging-method-uses-shadows-reconstruct-video-projected-unseen-part-room) Researchers from the [CSAIL](https://www.trendhunter.com/trends/mouthio) lab at MIT created a way to use shadow footage to see around corners with computational mirrors. The system uses an algorithm that is able to synthesize what could be occurring away from a camera. The team of researchers ran an experiment where filming was being done on a pile of objects, away from the filming objects were being moved. The algorithm was then able to use the shadow footage to determine what was occurring off-screen. MIT’s experiment has applications for [self-driving cars attempting to park themselves](https://www.trendhunter.com/trends/collision-prevention-system). This is because a self-driving system would need to be able to determine what is on the other side of a corner. Previously MIT looked into seeing around corners, however, this system is better as it does not require a [laser camera](https://www.trendhunter.com/trends/lidar-systems) to operate.
