Análise comparativa entre a primeira e a segunda versão do Kinect na biometria do caminhar

Abstract

The main goal of this thesis is to bring a comparative between the two versions of the Kinect sensor in biometric identification through human gait. To compare the sensors, four different methods of human gait parameters extraction were implemented, being analyzed both anthropometric, kinematic and spatiotemporal attributes. An individual analysis of each attribute of the gait characterization methodologies was performed to identify the attributes that bring the greatest contribution in the identification of individuals. In order to create a base for extracting gait parameters, 50 individuals were captured through the Kinect sensors and machine learning algorithms were applied to classify the people. The results obtained show a superiority of Kinect One in most of the methodologies, justifying its use in relation to Kinect 360. In this work, a mapping between the sensors in relation to the identification of the individual’s gender and an analysis of the pose dependency were also performed as additional experiments.
