opencv：使用dlib/face++ 人臉關鍵點檢測

人臉關鍵點檢測

人臉，是人身份的一種關鍵信息。從古代來說，會有面相之說。有的說，一個人心裏怎麼樣，就會長得怎麼樣，相由心生。據說，這一些經驗也被應用於警察在路邊抽查的時候，比如賊眉鼠眼等等的樣子，就容易受到盤問。

這種靠經驗總結的傳統信息在現在這個時代可能會有些用，但隨着科技的發展，那麼，人臉到底是如何被應用於現代科技上面的呢？答案是依靠人臉關鍵點。人臉關鍵點檢測是人臉在工業應用中一個比較重要的基礎性研究，可以說，大多數的人臉相關業務都是在此基礎上進行的二次開發。比如人臉識別，試妝算法，人臉融合等。人臉的關鍵點檢測的好壞，直接影響後續的業務。

“人臉關鍵點檢測”的圖片搜索結果

目前很多公司都有關於人臉關鍵點檢測的api的業務，比如騰訊雲，百度雲，face++等。這裏不做過多的介紹，只是講解一下，利用opencv的包dlib以及調用face++的接口，展示一下人臉關鍵點檢測大致概念。

使用dlib進行人臉關鍵點檢測

dlib封裝了一個人臉關鍵點提取算法，下載好模型後可直接調用。目前是實現的是68點 關鍵點檢測：
68
（68點）

使用face++ APi接口進行人臉關鍵點檢測

face++ 實現了83點以及106點的關鍵點檢測，直接去官網申請賬號，進行調用接口就行。

python-opencv-人臉對齊和反對齊

背景描述 我需要將視頻中的圖像拆幀後對齊到標準人臉上，進行一些算法加工後在反對齊回原始視頻裏。對齊人臉主要依賴於仿射變換，即根據lmks中的5個關鍵點（眼睛眉毛）找出仿射變換矩陣，再將原img中的所有像素點變換到標準人臉上，反對齊

人臉算法

人臉檢測 人臉檢測的目標是找出圖像中所有的人臉對應的位置，算法的輸出是人臉外接矩形在圖像中的座標，可能還包括姿態如傾斜角度等信息。 傳統方法 早期的人臉檢測算法使用了模板匹配技術，即用一個人臉模板圖像與被檢測圖像中的各個位置進行匹
