The automatic inspection of steel surface defects makes it possible to ensure the quality of products in the steel industry with high accuracy. However, the optimization of inspection time presents a great challenge for the integration of machine vision in high-speed production lines. In this context, compressing the collected images before transmission is essential to save bandwidth and energy, and improve the latency of vision applications. The aim of this paper was to study the impact of quality degradation resulting from image compression on the classification performance of steel surface defects with a CNN. Image compression was applied to the Northeastern University (NEU) surface-defect database with various compression ratios. Three different models were trained and tested with these images to classify surface defects using three different approaches. The obtained results showed that trained and tested models on the same compression qualities maintained approximately the same classification performance for all used compression grades. In addition, the findings clearly indicated that the classification efficiency was affected when the training and test datasets were compressed using different parameters. This impact was more obvious when there was a large difference between these compression parameters, and for models that achieved very high accuracy. Finally, it was found that compression-based data augmentation significantly increased the classification precision to perfect scores (98\u2013100%), and thus improved the generalization of models when tested on different compression qualities. The importance of this work lies in exploiting the obtained results to successfully integrate image compression into machine vision systems, and as appropriately as possible.<\/jats:p>","DOI":"10.3390\/jsan10040073","type":"journal-article","created":{"date-parts":[[2021,12,16]],"date-time":"2021-12-16T21:32:40Z","timestamp":1639690360000},"page":"73","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Impact of Image Compression on the Performance of Steel Surface Defect Classification with a CNN"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7099-6726","authenticated-orcid":false,"given":"Tajeddine","family":"Benbarrad","sequence":"first","affiliation":[{"name":"Laboratory of Information and Communication Technologies (LabTIC), National School of Applied Sciences of Tangier, Abdelmalek Essaadi University, Tangier 90000, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lamiae","family":"Eloutouate","sequence":"additional","affiliation":[{"name":"Laboratory of Informatics Systems and Telecommunications (LIST), Faculty of Sciences and Technologies of Tangier, Abdelmalek Essaadi University, Tangier 90000, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mounir","family":"Arioua","sequence":"additional","affiliation":[{"name":"Laboratory of Information and Communication Technologies (LabTIC), National School of Applied Sciences of Tangier, Abdelmalek Essaadi University, Tangier 90000, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fatiha","family":"Elouaai","sequence":"additional","affiliation":[{"name":"Laboratory of Informatics Systems and Telecommunications (LIST), Faculty of Sciences and Technologies of Tangier, Abdelmalek Essaadi University, Tangier 90000, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"My Driss","family":"Laanaoui","sequence":"additional","affiliation":[{"name":"Laboratory of Computer and Systems Engineering (L2IS), Higher Normal School, Cadi Ayyad University of Marrakech, Marrakech 40000, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"127052","DOI":"10.1016\/j.jclepro.2021.127052","article-title":"Industry 4.0 ten years on: A bibliometric and systematic review of concepts, sustainability value drivers, and success determinants","volume":"302","author":"Ghobakhloo","year":"2021","journal-title":"J.
