Together with the University of Georgia Tech researchers developed an algorithm that adjusts the aspect ratio of videos, clipping off pages to attach black bars or stretch or shrink the image easily.

These are objects that are in the foreground as actors or faces recognized in the image. The image is for resources that are in the foreground and those that do not split up. Now if the aspect ratio adjusted to keep the content to the fore largely untouched, since a change would be noticeable to the viewer.
