Video synopsis

When a summary is required, all objects from the target period are collected and shifted in time to create a much shorter synopsis video showing maximum activity.

Objects are detected and stored in a database in approximately real time.

Real time rendering is used to generate the summary video after object re-timing.

In May 2018, BriefCam was acquired by Japanese digital imaging giant, Canon Inc., for an estimated $90 million.

These methods have been shown to work well for egocentric[10] settings where the video is basically a point-of-view perspective of a single person or a group of people.

Video synopsis example: 9 hours of activity summarized in a 20-second simultaneous presentation of multiple objects and activities that occurred at different times.
