Synopsis frames and manufacturing method thereof

Abstract

A synopsis video includes a plurality of synopsis frames manufactured by using plural chronological source frames which include a plurality of foreground objects. Each of the foreground objects appearing in one of the synopsis frames just exists at one position of the synopsis frame. At least one portion of the foreground objects appearing in one of the synopsis frames originates from the source frames of different times. One of the foreground objects that originates from a later source frame appears in a later synopsis frame, and the foreground object that originates from a former source frame appears in a former synopsis frame.

Description

technical field [0001] The invention relates to an image manufacturing method, in particular to an abstract image manufacturing method and an abstract image. Background technique [0002] In order to monitor the environment of daily life, surveillance cameras can be seen everywhere, and the demand for surveillance systems is also increasing. In order to be able to fully record the course of all events, long-term video recordings require a very large storage space for future reference. Although the current storage devices are getting cheaper and cheaper, there is no way to expand without limit, so the old data must be overwritten in order to record new data. Frequently overwriting old data has the consequence of reducing the amount of information that can be recorded if information retention is not efficient enough. Of course, video compression technology can also be used to achieve the purpose of reducing storage space, but video compression technology also has a limit. I...

AI Technical Summary

Problems solved by technology

Although the current storage devices are getting cheaper and cheaper, but there is no way to expand without limit, so it is bound to overwrite the old data in order to record new data

The consequence of often overwriting old data is to reduce the amount of information that can be recorded if information retention is not efficient enough

Of course, video compression technology can also be used to achieve the purpose of reducing storage space, but video compression technology also has a limit

In addition, it is also very difficult to effectively obtain information from a long video. Even if the video is used to speed up playback, it will only sacrifice the information contained in the original video.
