Human Motion Recognition from Multiple Directions and Its Gait Cycles Analysis

It is crucial for individuals to keep walking and stay healthy to prevent receiving nursing care.This paper proposes a method of recognizing walk motions and analyzing the gait cycle of a human focusing on his/her posture.We use 43 structural features defined from human joint coordinates obtained using OpenPose and 18 figural features from human domain images and their difference images.The feature vector containing these 61 features is used for the recognition of walk motion by Random Forest.In the experiment, we applied the method to recognizing six types of motions and analyzed the walk gait cycles of five persons, and obtained satisfactory results.
