opencv2.2.0源代码（include文件）分析
由于openCV2.2.0源文件很龐大，這里我只分析openCV2.2.0文件組織結構的各個模塊的include文件（重點分析各個模塊下引用的算法和實現的功能），而不是src文件。這里分析各個模塊有助于更好的從整體把握和理解openCV2.2.0。這里只是自己做草稿部分，便于以后修改查找。有理解不對的，希望大家指出。--瘋子_007
?
首先分析的是highgui目錄下的highgui_c.h和highgui.cpp文件：
highgui_c.h分三部分：基本的GUI函數庫，視頻接口，和過時的函數庫。基本的GUI函數庫包括：創建窗體，設置窗體屬性，獲取窗體屬性，在窗體內顯示圖片，改變窗體大小，移動窗體，銷毀窗體（包括銷毀所有窗體）；獲取給定句柄的窗體名，創建和顯示滾動條，恢復和設置滾動條位置；鼠標回調事件，設置鼠標事件回調，枚舉鼠標類型；載入圖片，保存圖片，改變圖片結構；按鍵等待。視頻接口包括：定義攝像頭結構，通過視頻文件獲取幀，從攝像頭獲取視頻文件，幀處理的特殊函數（cvRetrieveFrame），抓取幀，釋放視頻文件；恢復或者設置攝像頭屬性，返回攝像頭類型；定義寫視頻指針結構體，四色編碼，打開編碼屬性對話框，初始化寫視頻指針，將幀流寫入寫視頻指針，釋放寫視頻指針。過時的函數庫。將一些功能相同的函數，重新命名，保持舊代碼的連接性。
highgui.cpp在CV命名空間枚舉相應的一些函數和定義了VideoCapture，VideoWriter類，采用面向對象的思想進行編程，更容易理解和整體把握。

前面的是一些宏定義，是為了兼容C，C++。對于一些函數的調用方式，建議補充一點補充知識：http://blog.csdn.net/yongdun_007/archive/2010/12/21/6090281.aspx，這個頭文件是很重要的一個文件，建議大家都看看，這里定義了opencv用到的所有的數據類型和結構。詳細如下：
types_c.h包括：常用的宏指令和內聯函數，隨機數的生成，圖像數據類型，矩陣數據類型，多維稠密矩陣，多維稀疏矩陣，稀疏矩陣迭代，直方圖，其他數據類型定義（包括矩形，終止準則，點和變量，size變量和Box變量，片和部分，尺度或者角度），動態數據結構（包括內存存儲，序列，節點或者集，圖結構，鏈和輪廓），序列類型，序列的讀/寫操作，對序列的操作（包括圖的微操作），保持數據結構的穩定性，系統數據類型。
