基于多尺度特征融合與自適應(yīng)網(wǎng)絡(luò)的小目標(biāo)檢測(cè)方法研究

基于多尺度特征融合與自適應(yīng)網(wǎng)絡(luò)的小目標(biāo)檢測(cè)方法研究摘要：

隨著計(jì)算機(jī)視覺(jué)技術(shù)的不斷發(fā)展，小目標(biāo)檢測(cè)一直是人們關(guān)注的熱點(diǎn)研究領(lǐng)域。小目標(biāo)檢測(cè)不僅與智能監(jiān)控、軍事偵察等領(lǐng)域密切相關(guān)，而且具有廣泛的應(yīng)用前景。由于小目標(biāo)通常具有尺寸小、形狀復(fù)雜、紋理簡(jiǎn)單等特點(diǎn)，因此對(duì)于小目標(biāo)的檢測(cè)和識(shí)別一直是計(jì)算機(jī)視覺(jué)領(lǐng)域的難點(diǎn)之一。本文提出了一種基于多尺度特征融合與自適應(yīng)網(wǎng)絡(luò)的小目標(biāo)檢測(cè)方法。該方法主要分為兩個(gè)階段：首先使用多尺度特征提取器對(duì)圖像進(jìn)行特征提取，在保證尺度的同時(shí)提取包含小目標(biāo)的局部特征；然后利用自適應(yīng)網(wǎng)絡(luò)對(duì)不同尺度下的特征進(jìn)行融合，從而得到具有高精度和魯棒性的小目標(biāo)檢測(cè)結(jié)果。實(shí)驗(yàn)結(jié)果表明，所提出的方法具有優(yōu)異的檢測(cè)性能，不僅能夠檢測(cè)到目標(biāo)物體的位置，還能夠識(shí)別目標(biāo)物體的類(lèi)別。

關(guān)鍵詞：小目標(biāo)檢測(cè)，多尺度特征提取，自適應(yīng)網(wǎng)絡(luò)
