Abstract: A non-transitory computer-readable recording medium has stored therein verification program that causes a computer to execute a process including, acquiring an image captured by a camera, estimating, based on skeleton recognition of a person included in the acquired image, a chronological position of a skeleton of the person, estimating a first height of the person based on a parameter of the camera, correcting the estimated position of the skeleton of the person by using the estimated first height of the person and a first pixel length to be a reference per pixel constituting the image and performing verification of the person based on the corrected chronological position of the skeleton of the person.

Abstract: A non-transitory computer-readable recording medium stores an identification program for causing a computer to execute a process including: acquiring image data captured by a camera; generating skeleton information of a person included in an image frame and attribute information of the person included in the image frame by analyzing the image frame that constitutes the acquired image data; setting a first feature amount related to a height of the person for the person in the image frame based on the generated attribute information of the person; setting a second feature amount related to the height of the person for the person in the image frame based on the generated skeleton information; and specifying a parameter of the camera based on a difference between the first feature amount and the second feature amount.

Abstract: A filtering method includes converting two-dimensional skeleton coordinates obtained through skeleton detection on a two-dimensional video, into three-dimensional skeleton coordinates, specifying, with reference to degree-of-influence data in which a degree of influence of each joint on an error in two-dimensional-to-three-dimensional coordinate conversion is associated with each of inclination classes that are sectioned in accordance with an inclination of a body axis, an estimated value of the error from the three-dimensional skeleton coordinates and from a degree of influence of each joint that corresponds to an inclination class to which the three-dimensional skeleton coordinates belong, removing three-dimensional skeleton coordinates for which the estimated value of the error is greater than or equal to a threshold.
