To ensure the correct operation of detection tools based on the neural tracker, the following image requirements should 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 does must not exceed 75% of the frame size.
3. The image is not Image isn't noisy and not isn't distorted by compression algorithm artifacts.
4. The duration of the object's visibility is at least 6 six frames. 
5. 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).
6. The minimum value of pixel density per meter is observed:

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

the

7. object width in pixels to

the

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

the

9. object width to

the

10. 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%
    1280x720	Light vehicle (2 axles)	35	~240x205	~20%
    640x360	Light vehicle (2 axles)	17	~132x112	~20%
