To ensure the correct operation of Neurocounterthe neurocounter, the following image requirements should must be met:

  1. The detected object to must be detected is clearly distinguishable by the human eye.
  2. The width or height of the objects
  3. does
  4. must not exceed 75% of the frame size.
  5. The image is not Image isn't noisy and not isn't distorted by compression algorithm artifacts.
  6. The duration of the object's visibility is at least
  7. 6
  8. six frames. 
  9. The An object moves must move in the a certain direction between two adjacent frames at a distance which does not exceed the object's that doesn't exceed its size. This condition is necessary for the correct calculation of the object trajectory of the object (track).
  10. The minimum value of pixel density per meter is observed:
