| Abstract | When the faces of individuals are not clearly identifiable in surveillance videos due to variations in poses, camera viewpoints and occlusions, the appearances of people play a vital role in their identification. Appearance based person re-identification (re-id) summarizes appearances of persons to identify them across multiple non-overlapping camera views. Existing person re-id solutions work on the cropped person images to learn the salient features of a person instead of working on the raw surveillance images, hence these solutions need an independent preliminary phase of preparing cropped person datasets for the training and evaluation purposes. In contrast, the proposed solution works on the raw surveillance images instead of prerequisite of the cropped person dataset and the proposed hierarchical association building among various local parts of the images results in rich person representations for person re-id. In the proposed solution of Smart Surveillance with Simultaneous Person Detection and Re-identification (SSPDR), the complete surveillance video scenes are processed to perform simultaneous person detection and re-identification for all of the persons captured by a surveillance network. We use region proposals based localization scheme for person detection with an increased confidence strategy about the estimation of bounding boxes locations and the person re-identification module learns the hierarchical associations among local salient body parts of a person. Firstly, the proposed re-id module establishes associations among local horizontal strips of two persons, and afterwards it builds associations among local salient sub-patches of already associated pairs of horizontal strips. We address two major re-id challenges i.e. background noise and scale differences using the proposed re-id solution. In context of simultaneous person detection and re-identification, the proposed method is evaluated on publicly available re-id benchmark Person Re-identification in Wild (PRW) as well as on a local surveillance dataset, and attains state-of-the performance. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature. |
