This method usually takes a long time, is expensive, and is difficult to carry out for timely monitoring of crop diseases, causing delays to diagnosis and treatment. With the emergence of edge computing, one can attempt to deploy the pattern recognition algorithm to the farmland environment and monitor the growth of crops promptly. However, due to the limited resources of the edge device, the original deep recognition model is challenging to apply. Due to this, in this article, a recognition model based on a depthwise separable convolutional neural network (DSCNN) is proposed, which operation particularities include a significant reduction in the number of parameters and the amount of computation, making the proposed design well suited for the edge. To show its effectiveness, simulation results are compared with the main convolution neural network (CNN) models LeNet and Visual Geometry Group Network (VGGNet) and show that, based on high recognition accuracy, the recognition time of the proposed model is reduced by 80.9% and 94.4%, respectively. Given its fast recognition speed and high recognition accuracy, the model is suitable for the real-time monitoring and recognition of crop diseases by provisioning remote embedded equipment and deploying the proposed model using edge computing.<\/jats:p>","DOI":"10.3390\/s20154091","type":"journal-article","created":{"date-parts":[[2020,7,23]],"date-time":"2020-07-23T11:26:01Z","timestamp":1595503561000},"page":"4091","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Recognition of Crop Diseases Based on Depthwise Separable Convolution in Edge Computing"],"prefix":"10.3390","volume":"20","author":[{"given":"Musong","family":"Gu","sequence":"first","affiliation":[{"name":"College of Information Science and Technology, Chengdu University, Chengdu 610106, China"},{"name":"School of Information and Communication Engineering, University of Electronic Science and Technology of China, Chengdu 611731, China"},{"name":"Key Laboratory of Pattern Recognition and Intelligent Information Processing, Institutions of Higher Education of Sichuan Province, Chengdu University, Chengdu 610106, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1381-4364","authenticated-orcid":false,"given":"Kuan-Ching","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, Providence University, Taichung 43301, Taiwan"},{"name":"School of Computer Science and Engineering, Anhui University of Science and Technology, Huainan 232001, China"}]},{"given":"Zhongwen","family":"Li","sequence":"additional","affiliation":[{"name":"College of Information Science and Technology, Chengdu University, Chengdu 610106, China"}]},{"given":"Qiyi","family":"Han","sequence":"additional","affiliation":[{"name":"College of Information Science and Technology, Chengdu University, Chengdu 610106, China"}]},{"given":"Wenjie","family":"Fan","sequence":"additional","affiliation":[{"name":"College of Information Science and Technology, Chengdu University, Chengdu 610106, China"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"26971","DOI":"10.1109\/ACCESS.2018.2833632","article-title":"Coverage and connectivity in WSNs: Survey, research issues and challenges","volume":"6","author":"Tripathi","year":"2018","journal-title":"IEEE Access"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"30","DOI":"10.1109\/MC.2017.9","article-title":"The emergence of edge computing","volume":"50","author":"Satyanarayanan","year":"2017","journal-title":"Computer"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"637","DOI":"10.1109\/JIOT.2016.2579198","article-title":"Edge computing: Vision and challenges","volume":"3","author":"Shi","year":"2016","journal-title":"IEEE Internet Things J."},{"key":"ref_4","doi-asserted-by":"crossref","unstructured":"Zhu, X., Li, K., Zhang, J., and Zhang, S.
