MIT project uses camera and AI to 'record' hidden objects using the shadows they cast

Researchers with MIT's Computer Science & Artificial Intelligence Laboratory (CSAIL) have published a study detailing the use of cameras and artificial intelligence to recreate hidden actions based only on the shadows they cast. The method produces fairly low-quality results at this time but may be refined for future computational photography purposes that include helping self-driving cars 'see' hidden objects in their environment. Shadows can reveal the presence of things a person may not be ab...
