aliasing是英語中的動詞和名詞,發音為英[ˈeɪlɪəsɪŋ]、美[ˈeliəsɪŋ; ˈeljəsɪŋ],主要套用於信號處理與計算機圖形學領域。作為動詞時意為錯誤識別信號頻率;作為名詞指信號採樣中因頻率不足導致的混疊失真,或計算機圖像邊緣的鋸齒現象。該術語也指代使用替換名訪問計算機檔案或記憶體數據的操作。
在技術套用中,aliasing衍生出抗鋸齒技術(anti-aliasing)與抗混疊濾波器(anti-aliasing filter),分別用於改善圖像邊緣平滑度與消除高頻信號失真。相關概念包括頻率混疊(frequency aliasing)與混疊失真(aliasing distortion)等技術辭彙。硬體設備如DE Interlace Aliasing Reducer通過特定技術減少動態影像的掃描線失真。其理論與套用涉及奈奎斯特定理,如採樣率不足導致的摺疊失真現象及梯度域技術的解決方案。
