The observation of objects located in inaccessible regions is a recurring challenge in a wide variety of important applications. Recent work has shown that indirect diffuse light reflections can be used to reconstruct objects and two-dimensional (2D) patterns around a corner. However, these prior methods always require some specialized setup involving either ultrafast detectors or narrowband light sources. Here we show that occluded objects can be tracked in real time using a standard 2D cameradoi:10.1038/srep32491 pmid:27577969 pmcid:PMC5006175 fatcat:qewpml6rhnhjra7z3j4oeyrp7e
