Shape from motion only

2017 First prize
Hedva Spitzer, Dana Tearosh, Niv Weisman: “Shape from motion only”. School of Electrical Engineering. The Iby and Aladar Fleischman Faculty of Engineering. Tel Aviv University. Israel

Author description: The phenomenon “Shape from Motion Only” presented in its purest form in the video i.e., the information is only in the temporal domain, without any clues in the spatial domain. Both the object and the background are created by flashing the pixels on and off, while the only difference is expressed in the temporal properties. We examined various properties of the phenomenon such as: statistics and object size. Furthermore, we examined how several known optical illusions like “Rubin’s Vase” might occur using this temporal phenomenon. This research has the potential to open a hatch for better understanding the visual system mechanisms.
