摘要： An information processing apparatus and the like capable of calculating a respiratory feature amount necessary for evaluating a breathing motor function of a subject is provided. The information processing apparatus inputs time-series distance image data acquired by measuring a distance from the subject during a breathing exercise and division position data indicating a position at which a chest region and an abdominal region of the subject are divided in the time-series distance image data. The information processing apparatus calculates a standard deviation image indicating a standard deviation of values for each pixel in a distance image indicated by the time-series distance image data. The information processing apparatus calculates a respiratory feature amount indicating a feature of breathing of the subject, based on a divided standard deviation image acquired by dividing the standard deviation image for each divided region being divided at a position indicated by the division position data.

摘要： To provide an information processing apparatus and the like that are capable of dividing an image indicating movement of a subject into a chest region and an abdominal region along anatomical knowledge. The information processing apparatus inputs time-series distance image data acquired by measuring a distance from a subject during a breathing exercise. The apparatus calculates a standard deviation image indicating a standard deviation of values for each pixel in a distance image indicated by the time-series distance image data. The apparatus executes division processing of dividing the standard deviation image into the chest region and the abdominal region of the subject by using a differential value in a direction of an intersection line between a sagittal plane and a frontal plane of the subject with respect to the standard deviation image. The apparatus outputs a result of the division processing by superimposing the result on the standard deviation image.
