Abstract
A method includes: executing acquisition processing that includes acquiring an image frame captured by an imaging apparatus; executing a determination processing that includes determining whether a head region is included in the acquired image frame; executing calculation processing that includes calculating a first amount of change in time series of the head region by using a position of the head region in the image frame and a position of the head region in another image frame following the image frame; executing determination processing that includes determining a threshold to be compared with the first amount of change based on a frequency distribution of amounts of change in time series of the head region in a past image frame group prior to the acquired image frame; and executing evaluation processing that includes evaluating the first amount of change by comparing the determined threshold and the first amount of change.
