Efficient Scene Analysis of Recorded Video
Search of recorded video, “in a nutshell’; the video strea from a camera is processed in real time. Simultganeously, metadata about all objects mov ing in the frame and their movements is recorded to a separate database. No pre-configuration is necessary. To search, the user specifies event criteria (similarly to detection tool configuration), such as line crossing or motion in zone. Forensic search sorts through the recorded metadata and just seconds later locates all video fragments that match the criteria specified.
SEARCH CRITERIA
The interactive GUI allows dynamically selecting search options. Search criteria resemble the scene analysis detection tools in Intellect, such as line crossing and motion in zone. All detection tool types are available here too, with the exception of polyline crossing. With Forensic Search, users can also search for movement from a selected zone to another selected zone, and select the color of the object to find.
PERSPECTIVE OPTIONS
Tracking is now more useful thanks to configurable perspective options. As a result, objects can be classified by size more accurately, making tracking more precise both for foreground and for background objects.
WHY USE FORENSIC SEARCH
Quickly find events of interest in recorded video – find the needle in the “video haystack” – even when the precise time of an event is unknown. Forensic Search takes video archive operations to a new level: instead of spending hours rewatching a tape, search through recorded video by criteria and perform follow-up searches as necessary in near-real time.
BENEFITS
- No pre-configuration of detection tools required: information is saved about all moving objects. This is especially valuable for larger systems, since Forensic Search can be installed and configured without significant time or labor investments.
- Since search is run on previously recorded metadata, search can be repeated several times with refined criteria.
- High speed. Search is performed in near-real time, with the first results returned almost instantly
