To ensure the correct operation of detection tools based on the neural tracker, the following image requirements should be met:

  1. The object to be detected is clearly distinguishable by the human eye.
  2. The width or height of the objects does not exceed 75% of the frame size.
  3. The image is not noisy and not distorted by compression algorithm artifacts.
  4. The duration of the object's visibility is at least 6 frames. 
  5. The object moves in the certain direction between two adjacent frames at a distance which does not exceed the object's size. This condition is necessary for the correct calculation of the 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 object width in pixels to the object width in meters)

    		Minimum object size in pixels, width x heightRatio of the object width to the frame width as a percentage
