Image requirements for the Privacy masking

Hardware requirements for neural analytics operation

Requirements for the Make sure the following requirements are met for the correct operation of thePrivacy masking detection tool are given in the table:

Camera

...

  • Resolution is at least

...

  • 320х240 pixels

...

...

  • FPS is at least 1

...

  • Camera shake

...

  • doesn't

...

  • result in image

...

  • offsets greater than 1% of the frame size
Note
titleAttention!

Correct operation of the detection tool isn't guaranteed if you use frames that were masked before they got into Axxon One by an IP camera or similar methods.

 
Lighting

...

  • Moderate lighting.

...

  • In conditions of

...

  • insufficient (night) or excessive lighting (

...

  • light-striking), the quality of analytics performance can decrease
  • No

...

  • abrupt changes in lighting

...

Scene and camera angle

...

  • Moving objects

...

  • are visually separable from each other

...

  • Background is mostly static and

...

  • doesn't change abruptly
  • Moving objects are

...

  • minimally obscured by

...

  • static objects in the scene (columns, trees,

...

  • and so on)

...

  • Analytics may not work correctly

...

  • if:

    • the analyzed scene have reflective surfaces and

...

    • sharp shadows from moving objects

...

The width and height of the objects in the image must not be less than 1% of the frame size (if resolution is at least 1920x1080 pixels) or 15 pixels (at lower resolutions).

...

The width and height of the objects in the image must not exceed 75% of the frame size.
