Using Saliency and Cropping to Improve Video Memorability
This work addresses the problem of making videos more memorable for viewers, which could benefit content creators and platforms, but it is incremental as it builds on existing saliency and cropping techniques.
The paper tackled improving video memorability by cropping frames based on image saliency, finding that dynamic cropping can enhance memorability scores, especially for initially low-memorability videos.
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.
