Thinning is the transformation of a digital image into a simplified, but topologically equivalent image. It is a type of topological skeleton, but computed using mathematical morphology operators. == Example == Let , and consider the eight composite structuring elements, composed by: : and , : and and the three rotations of each by , , and . The corresponding composite structuring elements are denoted . For any ''i'' between 1 and 8, and any binary image ''X'', define ::, where denotes the set-theoretical difference and denotes the hit-or-miss transform. The thinning of an image ''A'' is obtained by cyclically iterating until convergence: :. 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「Thinning (morphology)」の詳細全文を読む スポンサード リンク
