In addition to reducing the yield of the crop, the causal pathogens also produce mycotoxins that can contaminate the grain. The development of resistant wheat varieties is one of the best ways to reduce the impact of FHB. To develop such varieties, breeders must expose germplasm lines to the pathogen in the field and assess the disease reaction. Phenotyping breeding materials for resistance to FHB is time-consuming, labor-intensive, and expensive when using conventional protocols. To develop a reliable and cost-effective high throughput phenotyping system for assessing FHB in the field, we focused on developing a method for processing color images of wheat spikes to accurately detect diseased areas using deep learning and image processing techniques. Color images of wheat spikes at the milk stage were collected in a shadow condition and processed to construct datasets, which were used to retrain a deep convolutional neural network model using transfer learning. Testing results showed that the model detected spikes very accurately in the images since the coefficient of determination for the number of spikes tallied by manual count and the model was 0.80. The model was assessed, and the mean average precision for the testing dataset was 0.9201. On the basis of the results for spike detection, a new color feature was applied to obtain the gray image of each spike and a modified region-growing algorithm was implemented to segment and detect the diseased areas of each spike. Results showed that the region growing algorithm performed better than the K-means and Otsu\u2019s method in segmenting diseased areas. We demonstrated that deep learning techniques enable accurate detection of FHB in wheat based on color image analysis, and the proposed method can effectively detect spikes and diseased areas, which improves the efficiency of the FHB assessment in the field.<\/jats:p>","DOI":"10.3390\/rs11222658","type":"journal-article","created":{"date-parts":[[2019,11,14]],"date-time":"2019-11-14T10:56:34Z","timestamp":1573728994000},"page":"2658","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":83,"title":["Detection of Fusarium Head Blight in Wheat Using a Deep Neural Network and Color Imaging"],"prefix":"10.3390","volume":"11","author":[{"given":"Ruicheng","family":"Qiu","sequence":"first","affiliation":[{"name":"Key Laboratory of Modern Precision Agriculture System Integration Research-Ministry of Education, China Agricultural University, Beijing 100083, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1079-118X","authenticated-orcid":false,"given":"Ce","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Bioproducts and Biosystems Engineering, University of Minnesota, Saint Paul, MN 55108, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9249-8365","authenticated-orcid":false,"given":"Ali","family":"Moghimi","sequence":"additional","affiliation":[{"name":"Department of Bioproducts and Biosystems Engineering, University of Minnesota, Saint Paul, MN 55108, USA"}]},{"given":"Man","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Modern Precision Agriculture System Integration Research-Ministry of Education, China Agricultural University, Beijing 100083, China"}]},{"given":"Brian J.","family":"Steffenson","sequence":"additional","affiliation":[{"name":"Department of Plant Pathology, University of Minnesota, Saint Paul, MN 55108, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3409-758X","authenticated-orcid":false,"given":"Cory D.","family":"Hirsch","sequence":"additional","affiliation":[{"name":"Department of Plant Pathology, University of Minnesota, Saint Paul, MN 55108, USA"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"611","DOI":"10.1023\/A:1020635214971","article-title":"Toxigenic Fusarium species and mycotoxins associated with head blight in small-grain cereals in Europe","volume":"108","author":"Bottalico","year":"2002","journal-title":"Eur.
