基于三重低秩正則化的魯棒半監(jiān)督多標(biāo)記學(xué)習(xí)算法及其在圖像標(biāo)注中的應(yīng)用

圖像自動標(biāo)注技術(shù)在圖像檢索領(lǐng)域發(fā)揮著越來越重要的作用,逐漸成為計算機視覺的研究熱點。數(shù)字可視化技術(shù)的進(jìn)步和發(fā)展使得大量的圖像可以在網(wǎng)絡(luò)上獲取,用戶可以根據(jù)自己的喜好從存儲庫中檢索這些圖像,然而這些圖像大多數(shù)都沒有描述信息。圖像標(biāo)注的傳統(tǒng)做法是由人類來完成的,這是一種費時費力的標(biāo)注方法,也是一種過于主觀的標(biāo)注方法。另一個難點是解決低層視覺特征(顏色、形狀和紋理)與用于解釋圖像的高層語義特征之間的語義鴻溝問題。大多數(shù)圖像檢索方法是基于內(nèi)容的圖像檢索(CBIR)和基于標(biāo)簽的圖像檢索(TBIR)方法。CBIR通過提取圖像本身的顏色、紋理和形狀等特征,在低層特征上進(jìn)行工作,但由于語義鴻溝,一般用戶無法使用它。TBIR的工作原理是根據(jù)文本查詢和圖像的手工標(biāo)注之間的匹配來查找相關(guān)圖像。但是它高度依賴于標(biāo)簽的可用性和質(zhì)量。然而,手動標(biāo)注的標(biāo)記是主觀的、模糊的、有限且?guī)г肼暤摹=陙?該領(lǐng)域的研究已經(jīng)通過圖像自動標(biāo)注的方法(AIA),將低層圖像特征與高層語義之間的語義鴻溝聯(lián)系起來。自動圖像標(biāo)注算法假設(shè)采集的圖像樣本具有語義標(biāo)記和低層特征表示。該標(biāo)注方法使用機器學(xué)習(xí)算法,然后可以訓(xùn)練它使用低層特征進(jìn)行語義...
