Detected object image requirements for Person location tracker

To ensure the correct recognition of a person's posture, the following image requirements must be met:

1. The detected object must be clearly distinguishable by the human eye.
2. The detected object must be completely within the frame.
3. Image isn't noisy and isn't distorted by compression algorithm artifacts.
4. The duration of the object's visibility is at least two frames.

5. 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
   For pose detection
   1920x1080	Human	170	~102x309
   1280x720	Human	128	~77x233
   640x360	Human	80	~48x145
