APNET: ATTRIBUTE PARSING NETWORK FOR PERSON RE-IDENTIFICATION

Most person re-identification methods rely solely on the pedestrian identity for learning. Person attributes, such as gender, clothing colors, carried bags, etc, are however seldom used. These attributes are highly identity-related and should be capitalized fully. Thus, we propose Attribute Parsing Network (APNet), an architecture designed for both image and person attribute learning and retrievals. To further enhance the re-id performance, we propose to leverage saliency maps and human parsing to boost the foreground features, which when trained together with the global and local networks, resulted in more generic and robust encoded representations. This proposed method achieved state-of-the-art accuracy performance on both Market1501 (87.3% mAP and 95.2% Rank1) and DukeMTMC-reID (78.8% mAP and 89.2% Rank 1) datasets.
