AI Technical Summary

Technical Problem

Existing technologies face challenges in accurately determining human behavior in images due to incomplete detection of body parts or low detection reliability, particularly in crowded situations, leading to decreased inference accuracy.

Method used

A detection system that employs multiple machine learning models to infer behavior based on the positional relationships of detected body parts, selectively choosing a model that does not rely on undetected or unreliable body parts, ensuring accurate behavior determination.

Benefits of technology

Improves the accuracy of behavioral determination by utilizing appropriate machine learning models based on the availability and reliability of detected body parts, enhancing inference precision.

Abstract

To improve the accuracy of action determination on the basis of body portions of a subject detected in an image.SOLUTION: An action determination device includes: detection means that performs detection processing for detecting a plurality of types of body portions of a subject in an image; selection means that selects one of a plurality of determination methods for determining an action of the subject on the basis of a result of the detection processing, and in the selection means, each of the plurality of determination methods uses a positional relationship of two or more types of body portions among the plurality of types of body portions for determining the action; and control means that controls to determine the action of the subject in accordance with the determination method selected by the selection means.SELECTED DRAWING: Figure 2
