再分享一下我老師大神的人工智慧教程吧。零基礎！通俗易懂！風趣幽默！還帶黃段子！希望你也加入到我們人工智慧的隊伍中來！

opencv 分水嶺演算法

分水嶺演算法是一種簡單的影象分割演算法，具體是人為規定兩點 以兩點為例 然後把這兩點看做低谷，向裡面注水，不停地蔓延，直到兩點形成的湖交界。opencv自帶了這個程式。摘抄如下，其中我做了一些修改。本程式的目的是測試分水嶺演算法 include include include include usi...

OpenCV之分水嶺演算法

在許多實際的應用中，我們需要分割影象，但是無法從背景影象中獲得有用資訊。但是分水嶺演算法在這方面往往非常有效，它可以將影象中的邊緣轉化為 山脈 將均勻區域轉化為 山谷 這樣有助於分割目標。分水嶺演算法是一種記憶拓撲理論的數學形態學的分割方法，其基本思想是把影象看作測地學上的拓撲地貌，影象中每點畫素的...
