Due to the resemblance of the appearance of the vehicles on road, traditional methods could not perform well on vehicles with high similarity. In this paper, we utilize hypergraph representation to integrate image features and tackle the issue of vehicles re-ID via hypergraph learning algorithms. A feature descriptor can only extract features from a single aspect. To merge multiple feature descriptors, an efficient and appropriate representation is particularly necessary, and a hypergraph is naturally suitable for modeling high-order relationships. In addition, the spatiotemporal correlation of traffic status between cameras is the constraint beyond the image, which can greatly improve the re-ID accuracy of different vehicles with similar appearances. The method proposed in this paper uses hypergraph optimization to learn about the similarity between the query image and images in the library. By using the pair and higher-order relationship between query objects and image library, the similarity measurement method is improved compared to direct matching. The experiments conducted on the image library constructed in this paper demonstrates the effectiveness of using multifeature hypergraph fusion and the spatiotemporal correlation model to address issues in vehicle reidentification.<\/jats:p>","DOI":"10.1155\/2021\/6641633","type":"journal-article","created":{"date-parts":[[2021,3,19]],"date-time":"2021-03-19T00:20:07Z","timestamp":1616113207000},"page":"1-10","source":"Crossref","is-referenced-by-count":1,"title":["Vehicle Reidentification via Multifeature Hypergraph Fusion"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2464-5765","authenticated-orcid":true,"given":"Wang","family":"Li","sequence":"first","affiliation":[{"name":"College of Computer Science, Open University of China, Beijing, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6650-6790","authenticated-orcid":true,"given":"Zhang","family":"Yong","sequence":"additional","affiliation":[{"name":"Beijing University of Technology, Beijing, China"}]},{"given":"Yuan","family":"Wei","sequence":"additional","affiliation":[{"name":"College of Computer Science, Open University of China, Beijing, China"}]},{"given":"Shi","family":"Hongxing","sequence":"additional","affiliation":[{"name":"College of Computer Science, Open University of China, Beijing, China"}]}],"member":"311","reference":[{"volume-title":"DeepID3: Face Recognition with Very Deep Neural Networks","year":"2015","author":"Y.
