In this paper, two cascaded networks of vehicle attribute recognition are established to solve the two problems. For vehicle targets with normal size, the multitask cascaded convolution neural network MC\u2010CNN\u2010NT uses the improved Faster R\u2010CNN as the location subnetwork. The vehicle targets in the complex background are extracted by the location subnetwork to the classification subnetwork CNN for the classification. The implementation of this task decomposition strategy effectively eliminates the interference of the complex background in target detection. For vehicle targets with small size, the multitask cascaded convolution neural network MC\u2010CNN\u2010ST applies the network compression strategy and the multilayer feature fusion strategy to extract the feature maps. These strategies enrich the location information and semantic information of the feature maps. In order to optimize the nonlinear mapping ability and the hard\u2010to\u2010detect samples mining ability of the networks, the activation function and the loss function in the two cascaded networks are improved. The experimental results show that MC\u2010CNN\u2010NT for the normal targets and MC\u2010CNN\u2010ST for the small targets achieve the state\u2010of\u2010the\u2010art performance compared with other attribute recognition networks.<\/jats:p>","DOI":"10.1155\/2019\/6409630","type":"journal-article","created":{"date-parts":[[2019,12,6]],"date-time":"2019-12-06T23:35:32Z","timestamp":1575675332000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Vehicle Attribute Recognition for Normal Targets and Small Targets Based on Multitask Cascaded Network"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4385-1134","authenticated-orcid":false,"given":"Fang","family":"Liu","sequence":"first","affiliation":[]},{"given":"Yong","family":"Zhang","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2260-4617","authenticated-orcid":false,"given":"Hua","family":"Gong","sequence":"additional","affiliation":[]},{"given":"Ke","family":"Xu","sequence":"additional","affiliation":[]},{"given":"Ligang","family":"Cai","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2019,12,6]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1155\/2015\/720308"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1155\/2019\/9085238"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucom.2017.02.085"},{"key":"e_1_2_9_4_2","doi-asserted-by":"crossref","unstructured":"FerisR.
