使用Plant Village進(jìn)行深度學(xué)習(xí)和特征提取的植物病害檢測
發(fā)布時(shí)間：2021-10-30 19:43
本文利用深度學(xué)習(xí)和特征提取技術(shù)解決植物病害檢測問題。所有測試和實(shí)驗(yàn)都是使用開源數(shù)據(jù)集Plant Village進(jìn)行的。本文的主要工作是實(shí)現(xiàn)三種不同的深度學(xué)習(xí)模型,即Resnet 50,Google Net和VGG16,并找出其中最適合解決分類問題的網(wǎng)絡(luò)模型。眾所周知,世界人口約為70億,農(nóng)作物疾病是世界糧食供應(yīng)的關(guān)鍵問題,而超過90%的人無法使用能夠識(shí)別和解決植物病問題的工具或功能。如今,我們生活在一個(gè)由大規(guī)模技術(shù),主要網(wǎng)絡(luò)覆蓋,高端智能手機(jī)以及人工智能的發(fā)現(xiàn)和改進(jìn)所主導(dǎo)的世界中。將高端智能手機(jī)和基于深度學(xué)習(xí)的計(jì)算機(jī)視覺相結(jié)合成為了可能。人們將其定義為“智能手機(jī)輔助疾病診斷”。在深度學(xué)習(xí)領(lǐng)域,學(xué)者們已經(jīng)訓(xùn)練了多種架構(gòu)模型,其中一些模型的性能達(dá)到了99.53%以上。先前的研究是對每種模型分別進(jìn)行的,每個(gè)模型都產(chǎn)生自己的結(jié)果。但是,在我們的研究中,我們使用最新的技術(shù)將三個(gè)先前測試過的深度學(xué)習(xí)模型（Resnet50,Google Net,VGG16）和兩個(gè)分類器（SVM和KNN）組合在一起,以便比較獲得的結(jié)果并找出哪種模型能夠更準(zhǔn)確且更好地解決植物病害分類問題。在本文中,我們解決了這個(gè)問題。...
