最近在自學遊戲開發，所以博客就停下來沒有寫了，不過最近工作上要實現一些東西，所以這裏在作一些筆記，比較清晰度算法主要是爲了實現調焦，這記錄一下代碼，具體暫時不說了。

上面我對圖片進行了分開，每一個分割區域中圖片清晰度（肉眼）都是越來越模糊來排列的。對於清晰度選用，由於每一秒需要處理大概十幀以上數據，所以計算儘量不能有除法，開平方等，只能由少量的乘法，儘量全部都是加法和減法，這樣計算時間纔會短，就是時間複雜度不能太高。
對於清晰度選用，我們這裏需要兩個判定標準，一個用於粗調焦下，判定清晰度，一個用於精調焦下，清晰度判定，通過上面數據，我們才用的兩個清晰度方法，第一個是br2，另一個暫定從la2和gr中選擇，具體選擇，按照實際調焦結果。
