Video stream and scene requirements for the Object Tracker and its sub-tools

Hardware requirements for neural analytics operation

Requirements for the operation of Object Tracker and its sub-tools are given in the table:

Object images

  • Image isn't noisy and isn't distorted by artifacts of the compression algorithm

  • The width or height of objects in the image should not:

    • be less than 1% of the frame size (at resolutions no less than 1920x1080 pixels) or 15 pixels (at lower resolutions)

    • exceed 75% of the frame size

  • When you use a neurofilter, the minimum width or height of an object must be at least 5% of the width/height of the frame

  • When using the Abandoned Object detection tool:

    • abandoned objects must be clearly visible in the image

    • the width and height of objects in the image should not exceed 25% of the frame size

  • The speed of movement of objects in the image should not be less than 1 pixel per second

  • To the object to be detected, the duration of its visibility must be at least 8 frames

  • When the object moves between two adjacent frames in a certain direction, its distance of movement should not exceed its size. This condition is necessary for correct calculation of the object’s trajectory (track).
