    Abstract: An information processing device extracts, from an image taken by an imaging device, a human area in which it is determined that a human is present, acquires a representative value of first feature values, the first feature values being calculated by inputting, to a conversion function, each color of pixels included in a part of the human area, corrects, based on the representative value, a skin range indicating that a color indicated by a feature value acquired with the conversion function is a color of human skin, and determines whether a human is present in a part of the image acquired by the imaging device, based on whether a second feature value calculated with the conversion function for each of a plurality of pixels forming the part of the image is within the corrected skin range.

    Abstract: A reference value creating device includes processing circuitry configured to; vehicle-related information related to a vehicle; determine a road type of a road on which the vehicle is traveling on a basis of the acquired vehicle-related information; acquire feature amount information regarding a feature amount of an occupant of the vehicle calculated on a basis of a captured image including a range in which at least a face of the occupant of the vehicle is present; and create a reference value of the feature amount for estimating an alertness level of the occupant on a basis of the acquired feature amount information, and create, when the determined road type has changed, the reference value of the feature amount corresponding to the changed road type.
