  1. Maximal speed depends on the object size. Dependence of maximally available speed from the frame frequency for typical objects –person – person and car is given in the table:

    Frame frequency

    Maximally available speed of a person

    Maximally available speed of a car

    6 fps

    5 km/h

    40 km/h

    12 fps

    10 km/h

    85 km/h

    25 fps

    20 km/h

    170 km/h


    So, for example, if it is required to recognize people moving with speed till 10 km/h, the frequency 12 fps is enough.

  2. The minimal speed of object motion is to be such as the displacement of object image will be less than 1 pixel per frame. .
