1、基于圖像處理的蜜柑大小自動分級方法摘要：文章介紹了采用圖像處理技術(shù)進(jìn)行蜜柑大小自動分級的方法，利用CCD攝像機(jī)獲取蜜柑的樣本圖像，應(yīng)用MATLAB軟件實現(xiàn)對樣本圖像的背景去除、二值化、圖像平滑、特征量提取和圖像標(biāo)定等處理，參照蜜柑分級的國家標(biāo)準(zhǔn)完成蜜柑自動分級。經(jīng)試驗驗證表明，此方法分級精度高、速度快。關(guān)鍵詞：蜜柑；圖像處理；自動分級中圖分類號：TP39文獻(xiàn)標(biāo)識碼：A文章編號：1007-8320（2012）05-0207-03MandarinsizeoftheautomaticclassificationmethodbasedonimageprocessingT
