There exist two types of top-hat transform: The ''white top-hat transform'' is defined as the difference between the input image and its opening by some structuring element; The ''black top-hat transform'' is defined dually as the difference between the closing and the input image. Top-hat transforms are used for various image processing tasks, such as feature extraction, background equalization, image enhancement, and others. ==Mathematical definitions== Let $f:E\backslash mapsto\; R$ be a grayscale image, mapping points from an Euclidean space or discrete grid ''E'' (such as ''R''2 or ''Z''2) into the real line. Let $b(x)$ be a grayscale structuring element. Then, the white top-hat transform of ''f'' is given by: :$T\_w(f)=f-f\; \backslash circ\; b$, where $\backslash circ$ denotes the opening operation. The black top-hat transform of ''f'' (sometimes called the ''bottom-hat'' transform ) is given by: :$T\_b(f)=f\backslash bullet\; b-f$, where $\backslash bullet$ is the closing operation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Top-hat transform」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
