  • Publication number: 20210338109
    Abstract: A skeleton extraction unit (120) extracts skeleton information expressing in a time series a motion of a skeleton of a person from two-dimensional video data (161) obtained by capturing a walking movement of the person. A walk analysis unit (130) calculates walk analysis data (31) including arm swing information expressing an arm swing state of the person in walking and gait information expressing a gait state of the person in walking, using the video data (161). A determination unit (150) compares a determination threshold value (164) for determining a fatigue degree of the person with the walk analysis data (31) of the person, and determines the fatigue degree of the person using a comparison result. The determination threshold value (164) includes a threshold value of the arm swing information and a threshold value of the gait information.

  • Patent number: 9852329
    Abstract: A computer characterizes an area of interest in an event attended by an audience by receiving behavior information for an audience attending the event and event activity information for one or more areas in the event venue. The computer analyzes the audience behavior and event activity to determine the areas in the event venue to which the audience pays attention. The computer determines the objects in the areas in the event venue and determines one or more areas of interest based on the areas in the event venue to which the audience pays attention and the objects in the areas in the event venue to which the audience pays attention. The computer calculates a characteristic of the areas of interest in the event based on: the areas of interest, the objects in the areas in the event venue, and the analyzed audience behavior information related to the areas of interest.
