LittleScoobyMaster 0 Posted August 12, 2006 Does anyone know a good way to minimize the number of false alerts caused by tree shadows with a Geovision card (without using a PIR)? I'm monitoring a yard that has trees everywhere and although I can mask out the trees, I can't mask out the tree shadows as the tree shadows constantly sway in the wind and are all over the lawn that is being monitored, plus, not only do the tree shadows sway in the wind, but they move throughout the yard all day long depending on the suns position in the sky. Is this sort of situation very difficult to obtain accurate alerts with a Geovision system? Or do I just need to enable some options I normally don't use too often like object counting\detection\tracking, etc.? Share this post Link to post Share on other sites

LittleScoobyMaster 0 Posted August 12, 2006 Do you think that Geovision might someday offer features like IntrusionTrack? http://www.ioimage.com/objects/pdf/flyer.pdf http://www.ioimage.com/objects/pdf/ioTotalTrack.pdf IntrusionTrack™ is an intelligent module that watches with unblinking vigilance for intruders in surveillance video; IntrusionTrack™ doesn’t give intruders a chance. Built-in VTD“ technology detects intruders while ignoring distractions that cause false alarms, like small animals, swaying branches, cloud shadows, rain, snow, etc. Running analysis per pixel at a rapid rate of 30 times per second, it learns and adjusts using algorithms and built in sight-logic all while applying user-defined security policies, further preventing false alarms and saving security personnel from ongoing global sensitivity calibrations such as for growing shadows and light changes.

rory 0 Posted August 12, 2006 man you asking a little too much for the cost of a Geo package .. i dont know the cost of that particular one but i know the GE 4 channel version is somewhere like $20K retail. .. What you'd do though with Geo is split the signal to the Geo out into a seperate system that just uses this motion devices software. But yeah it would be sweet if Geo ever did do that ..

Thomas 0 Posted August 12, 2006 It's marketing speak. It sounds like they simply use the ability set zones which isn't new and I thought Geovision had. Share this post Link to post Share on other sites
freeflyer 0 Posted August 12, 2006 IVA (Intelligent Video Analysis) systems are available; there are a few on the market here in the UK; They start with the same type of features that Geo offers, like missing object etc; but some are becoming really advanced. The majority work on scene analysis & differentiation. Depending on what system you select they offer features from Number Plate Recognition (ANPR) ; object counting, tracking & tracing (Speed / Size / Direction) and now more impressively Object Classification. Some of the features available are for monitoring humans: Access control Access to restricted areas & perimeters Overcrowding Suspicious packages Suspect behaviour People too close to the platform edge at stations Others are aimed at motorways Stationary traffic & jams Traffic counting; Type of vehicles passing, Lane use Illegal overtaking & tail-gating (Watch out you badass drivers!) NeuroDynamics offer a system that does intelligent scene analysis (iSAS) GE does a system called VideoIQ - a Human detection surveillance technology that detects human activity; This one learns new backgrounds automatically to distinguish between people, cars, animals trees etc. Been designed to work outside as well in support of security guards in minimising false alarms & identify real threats (marketing says 95% accurate!) Dallmeier do one called the DI-Detector Hope this helps, I'm aiming to get a demo of these in the coming months; will be aiming to supply them in the future, Happy to report my findings to anyone interested in the true performance of these systems when I've done this Regardz - FreeFlyer Share this post Link to post Share on other sites
rory 0 Posted August 12, 2006 Yep VideoIQ has been around a for a few years now, the cost is in the area of what i mentioned above though. Share this post Link to post Share on other sites
freeflyer 0 Posted August 12, 2006 Hi Little ScoobyMaster; Thomas & Rory Some police forces are starting to install the Neorodynamics systems here on motorways; it's allowing the camera operators the ability to do more in less time by basically waiting for the software to tell them when a vehicle is doing something it shouldn't do; I'm sure we'll find these systems becoming increasing popular in the "BigBrother" world we are living in. Airports are obviously the target areas for IVA systems nowadays, but in a nutshell from a buyers perspective, the benefits are immense when you think one static guard may cost you 20,000 US$ for 8 hours a day monitoring and they might miss something, with one system at roughly the same cost (Retail) you get 24/7 protection with a 95% accuracy level. Surely it's only a matter of time until Geo starts to expand their software functions to include some of these more advanced analysis features isn't it? Still I reckon you get great value for money with a Geo system / software as it is, but with the costs of the alternatives becoming less every day the gap is decreasing, wont Geo have to keep expanding the Scene detection/ intelligent analysis features to keep up with the competition in the future anyway?

rory 0 Posted August 12, 2006 Nah, thats where the custom companies come in, add on PCs to the GEO ... GEO is too mass marketted DVR ... i dont think theyll end up going too specialised or the cost of their cards and software will rise .. Share this post Link to post Share on other sites
