Omnicast and BriefCam Video Synopsis^TM Technology Integration

With the integration of BriefCam Video Synopsis to Genetec’s IP video surveillance solution, Omnicast, users will be able to view and review hours of video recordings in mere minutes, considerably improving the quality of their daily security routines. BriefCam’s Video Synopsis technology fulfills the unmet global need to review video, quickly identify and investigate incidents, and take action.

What is BriefCam Video Synopsis™?

Video Synopsis is the simultaneous presentation of multiple objects, events and activities that have occurred at different times during the day. BriefCam Video Synopsis is a patented technology that summarizes hours of video surveillance recordings into a short brief that takes only minutes to review.

Genetec’s Omnicast IP Video Surveillance Solution with BriefCam Video Synopsis™

BriefCam VS Online is integrated with versions 4.4 and higher of Omnicast. BriefCam retrieves live video from Omnicast in real time to create an objects database that can be accessed on demand by operators, presenting events in a convenient, concise, easy-to-view format that is time stamped and indexed back to the original footage for further investigation.

BriefCam’s Video Synopsis Integration Process with Omnicast

Video Synopsis provides a very short video representation of a long time period, while preserving all essential activities of the original video. The synopsis serves as an index into the full video, and is performed in three stages.

1. In the Ingest stage, the live video is analyzed online. This process is taking place whilst video is being recorded to Omnicast. During this process all objects are separated into background (all static, non-moving objects) and foreground (moving objects), and all moving objects are being extracted. Descriptions of the extracted moving objects are inserted into a database located on the BriefCam server.
2. In the Synopsis stage, a user specifies a time period of interest (e.g., last 24 hours). Relevant objects and backgrounds for that specified period are extracted from the database. A very short synopsis video is then generated from these objects and backgrounds.
3. In the Indexing stage, the user selects an object of interest. This object then points to the original video, showing this object as it was originally recorded.

BriefCam’s Patented Video Synopsis^TM Technology

Video Synopsis is an approach to creating a short video summary of a long video. It tracks and analyzes moving objects (also called events), and converts video streams into a database of objects and activities.

Video Synopsis combines a visual summary of stored video together with an indexing mechanism. 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. A synopsis video clip is generated, in real time, in which objects and activities that originally occurred in different times are displayed simultaneously. (See Figure 1a-c - Screen shots: Before and after Video Synopsis).

The process begins by detecting and tracking moving objects. Each object is represented as a "tube" in "space-time" of all video frames. Objects are detected and stored in a database in approximate real time.

Following a request to summarize a time period, all objects from the desired time are extracted from the database, and indexed to create a much shorter summary video containing maximum activity. (See Figure 2 - Tube packing).

Real time rendering is used to generate the summary video after object re-timing. This allows end-user control over object/event density.

BriefCam Video Synopsis features at a glance:

• Objects are detected and stored in a database.
• Upon request, objects from the desired timeframe can be extracted from the database.
• Objects are indexed to create a summary video containing maximum activity.
• Real time rendering allows end-user control over object/event density.
