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

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

    Image resolution	Object type	Minimum pixel density per meter (ratio of

the

16. object width in pixels to

the

17. object width in meters)	Minimum object size in pixels, Width x Height	Ratio of

the

18. object width to

the

19. frame width as a percentage
    1920x1080	Human	55	~25x105	~3%
    1280x720	Human	35	~17x70	~3%
    640x360	Human	17	~10x42	~3%
    1920x1080	Light vehicle (2 axles)	55	~354x300	~20%
