Distortion Correction(失真校正) 指通過技術手段修正信號、圖像或物體因物理或系統因素導緻的變形、扭曲或失真的過程。以下是詳細解釋:
如需進一步了解某領域的具體方法,可參考來源網頁(如醫學影像詳見,圖像處理見)。
Distortion是指某個事物的形狀、聲音、圖像等因某種原因而變得扭曲或失真的狀态。在音頻和視頻領域中,distortion通常指音頻或視頻信號的失真,可以是由于傳輸或錄制設備的質量不佳,或者由于放大器過載等原因導緻的信號失真。
Correction是指對某種事物的錯誤或偏差進行調整或校正的行為。在音頻和視頻領域中,correction通常指對音頻或視頻信號進行調整以消除失真或其他音頻或視頻問題。
