It is easier than ever to restore the blurred content in the video.

Restoring the censored content in videos is easier than ever

Producer Jeff Geerling recently challenged his audience to uncover the video content hidden by the pixelation filter and promised a $50 reward. Three different people succeeded, but each relied on a similar principle. Specifically, pixelation is like a grid on a picture. When moving the image below, different parts of the picture can be glimpsed. As long as there is a solid reference frame, such as a window with a constant size, pixel data from the picture below can be "accumulated". With enough incomplete snapshots, AI can be used to piece together the content that the pixelation filter tried to hide. With the help of today's AI, it can be achieved even without very powerful computing power and professional knowledge reserves. This means that using solid color blocks and static images will be more effective in protecting the original content.
