It is widely used in image retrieval and target tracking. Shape context method, curvature scale space (CSS) operator and its improvement have been the main algorithms of shape matching and classification. The shape classification network (SCN) algorithm is proposed inspired by LeNet5 basic network structure. Then, the network structure of SCN is introduced and analyzed in detail, and the specific parameters of the network structure are explained. In the experimental part, SCN is used to perform classification tasks on three shape datasets, and the advantages and limitations of our algorithm are analyzed in detail according to the experimental results. SCN performs better than many traditional shape classification algorithms. Accordingly, a practical example is given to show that SCN can save computing resources.<\/jats:p>","DOI":"10.3390\/sym13030499","type":"journal-article","created":{"date-parts":[[2021,3,18]],"date-time":"2021-03-18T22:19:36Z","timestamp":1616105976000},"page":"499","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["SCN: A Novel Shape Classification Algorithm Based on Convolutional Neural Network"],"prefix":"10.3390","volume":"13","author":[{"given":"Chaoyan","family":"Zhang","sequence":"first","affiliation":[{"name":"Institute of Intelligent Control and Image Engineering, Xidian University, Xi\u2019an 710071, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yan","family":"Zheng","sequence":"additional","affiliation":[{"name":"Institute of Intelligent Control and Image Engineering, Xidian University, Xi\u2019an 710071, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baolong","family":"Guo","sequence":"additional","affiliation":[{"name":"Institute of Intelligent Control and Image Engineering, Xidian University, Xi\u2019an 710071, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3915-5451","authenticated-orcid":false,"given":"Cheng","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Intelligent Control and Image Engineering, Xidian University, Xi\u2019an 710071, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nannan","family":"Liao","sequence":"additional","affiliation":[{"name":"Institute of Intelligent Control and Image Engineering, Xidian University, Xi\u2019an 710071, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,18]]},"reference":[{"key":"ref_1","unstructured":"Mouine, S., Yahiaoui, I., and Verroust-Blondet, A.V.
