Appearance-Based Re-identification of People in Video

Abstract

This paper introduces the topic of appearance-based re-identification of people in video. This work is based on colour information of people’s clothing. Most of the work described in the literature uses full body histogram. This paper evaluates the histogram method and describes ways of including spatial colour information. The paper proposes a colour-based appearance descriptor called Colour Context People Descriptor. All the methods are evaluated extensively. The results are reported in the experiments. It is concluded at the end that adding spatial colour information greatly improves the re-identification results.
