Using Saliency and Cropping to Improve Video Memorability

Video memorability is a measure of how likely a particular video is to be
remembered by a viewer when that viewer has no emotional connection with the
video content. It is an important characteristic as videos that are more
memorable are more likely to be shared, viewed, and discussed. This paper
presents results of a series of experiments where we improved the memorability
of a video by selectively cropping frames based on image saliency. We present
results of a basic fixed cropping as well as the results from dynamic cropping
where both the size of the crop and the position of the crop within the frame,
move as the video is played and saliency is tracked. Our results indicate that
especially for videos of low initial memorability, the memorability score can
be improved.
