Detected object image requirements for neurocounter

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

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

   Image resolution	Object type	Minimum pixel density per meter (ratio of object width in pixels to object width in meters)	Minimum object size in pixels, Width x Height	Ratio of object width to 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%
