The key factors that influence the oil quality are ripening stages and the state of health of the fruit. For this reason, at the oil mill\u2019s reception yard, fruits are visually inspected and separated according to their external appearance. In this way, the process parameters can be better adjusted to improve the quantity and\/or quality of olive oil. This paper presents a proposal to automatically determine the oil quality before being produced from a previous inspection of the incoming fruits. Expert assessment of the fruit conditions guided the image processing. The proposal has been validated through the analysis of 74 batches of olives coming from an oil mill. Best correlation results between the image processing and the analytical data were found in the acidity index, peroxide values, ethyl ester, polyphenols, chlorophylls, and carotenoids.<\/jats:p>","DOI":"10.3390\/s18113826","type":"journal-article","created":{"date-parts":[[2018,11,9]],"date-time":"2018-11-09T03:08:02Z","timestamp":1541732882000},"page":"3826","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Fast and Reliable Determination of Virgin Olive Oil Quality by Fruit Inspection Using Computer Vision"],"prefix":"10.3390","volume":"18","author":[{"given":"Javiera","family":"Navarro Soto","sequence":"first","affiliation":[{"name":"Robotics, Automation and Computer Vision Group, Electronic and Automation Engineering Department, University of Jaen, ES-23071 Jaen, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0154-4125","authenticated-orcid":false,"given":"Silvia","family":"Satorres Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Robotics, Automation and Computer Vision Group, Electronic and Automation Engineering Department, University of Jaen, ES-23071 Jaen, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4150-5967","authenticated-orcid":false,"given":"Diego","family":"Mart\u00ednez Gila","sequence":"additional","affiliation":[{"name":"Robotics, Automation and Computer Vision Group, Electronic and Automation Engineering Department, University of Jaen, ES-23071 Jaen, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan","family":"G\u00f3mez Ortega","sequence":"additional","affiliation":[{"name":"Robotics, Automation and Computer Vision Group, Electronic and Automation Engineering Department, University of Jaen, ES-23071 Jaen, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Javier","family":"G\u00e1mez Garc\u00eda","sequence":"additional","affiliation":[{"name":"Robotics, Automation and Computer Vision Group, Electronic and Automation Engineering Department, University of Jaen, ES-23071 Jaen, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,8]]},"reference":[{"key":"ref_1","unstructured":"International Olive Council MARKET NEWSLETTER No 125\u2013MARCH 2018, 18, 1\u20136.
