If you come across a time hole, do not panic: How to fill it.

Time holes are in the news. The headline from Wired is typical:

Pentagon Scientists Use ‘Time Hole’ to Make Events Disappear

If you come across a time hole, do not panic. A study published several years ago tells how to fill that hole:

Space-Time Video Completion,” Y. Wexler, E. Shechtman, M. Irani,. Proceedings of the 2004 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2004, 27 June-2 July 2004, pp. I-120 – I-127. The authors, at the Weizmann Institute of Science, Rehovot, Israel, report:

“We present a method for space-time completion of large space-time “holes” in video sequences of complex dynamic scenes. The missing portions are filled-in by sampling spatio-temporal patches from the available parts of the video, while enforcing global spatio-temporal consistency between all patches in and around the hole.”
