This article describes the absolute minimum information we need in order to start analyzing and optimizing Video Analytics performance.
Video Analytics (VA) task performance optimization
Please provide the following details:
Symptom specific Information
Describe the expected result from the VA task.
It is important to get detailed information of the results VA should provide.
Define what is the customer’s priority:
High sensitivity - miss as few true alarms as possible, but increases the likelihood of more false alarms!
High precision – have less false alarms, but accept the risk to miss true alarm!
Using VA is always based on balancing between sensitivity and precision. It is not always possible to get high sensitivity and high precision at the same time.
