Sterile Zone Performance38 hours, PAL (720 x 576 x 25 fps), M-JPEG, 40 MbpsNumber of true positive alarms: a = 432

False positives alarms (type I error): b = 0

False negatives alarms (type II error): с = 0

Maximum response time

• People walking and running–2 seconds

• People moving slowly(e.g. crawling)–10 seconds

Causes of false negatives(simple motion detectors)

• Unstable background decreases sensitivity of an adaptive detector

DYNAMIC TEXTURE MODELING ALGORITHMSENABLE ROBUST OBJECT DETECTION IN A CHALENGING ENVIROMENT

Causes of false positives(basic motion detectors)

• Variable lighting– Shadows from moving clouds and sun– Moving trees, bushes and water

• Camera shaking• Animals, birds and insects• Object trajectory split and double detection• Snow, rain, fog

Examples of false positives(simple motion detectors)

ONVIF events and metadata

1. Tampering detectors– Video input quality control

2. Object tracker metadata– for server-side analytics and PTZ-targeting

3. Embedded rule engine events– Edge behavior recognition

4. Digital inputs and outputs– Dry contacts opened/closed, relay status

5. Device monitoring– Temperature, power, processor, memory, network
