Abstract

This paper presents a method that analyzes human behavior in a shopping setting. Several actions are detected and we are especially interested in detecting interactions between customers and products. This paper first presents our application context, the advantages and constraint of a shopping setting. Then we present and evaluate several methods for human behavior understanding. Human actions are represented with Motion History Image (MHI), Accumulated Motion Image (AMI), Local Motion Context (LMC), and Interaction Context (IC). Then we use Support Vector Machines (SVM) to classify actions. Finally, we combine LMC and IC descriptors in a real-time system that recognizes human behaviors while shopping to enhance digital media impact at the point of sale.
