Three-dimensional person behavior estimation

A processing method performed by a computer and comprising:

• generating, from a plurality of time-series images, three-dimensional feature information indicating a time change of a feature in each position in-each of the plurality of time-series images by inputting the plurality of time-series images to a CNN (Convolutional Neural Network), the CNN receiving input of the plurality of time-series images and outputting the three-dimensional feature information;
• generating person position information indicating a position in which a person is present in each of the plurality of time-series images;
• adjusting the three-dimensional feature information by changing a value in a position in which no person is present to a predetermined value based on the person position information;
• and
• estimating person behavior indicated by the plurality of time-series images, based on the adjusted three-dimensional feature information indicating the predetermined value in positions in which no person is present and indicating the time change of the feature in positions in which the person is present.

A non-transitory storage medium storing a program causing a computer to:

• generate, from a plurality of time-series images, three-dimensional feature information indicating a time change of a feature in each position in-each of the plurality of time-series images by inputting the plurality of time-series images to a CNN (Convolutional Neural Network), the CNN receiving input of the plurality of time-series images and outputting the three-dimensional feature information;
• generate person position information indicating a position in which a person is present in each of the plurality of time-series images;
• adjust the three-dimensional feature information by changing a value in a position in which no person is present to a predetermined value based on the person position information;
• and
• estimate person behavior indicated by the plurality of time-series images, based on the adjusted three-dimensional feature information indicating the predetermined value in positions in which no person is present and indicating the time change of the feature in positions in which the person is present.
