Person size is an area of the rectangle around a person as a percentage of the frame area. For the correct operation of the detection tool, you must select person size in the range from the minimum value depending on the frame width to 75% of the frame width.
The minimum size of a person, depending on the frame width, is given in the table:
| Frame width, px | Minimum size of a person in % |
