week14
課前準備
1 安裝 OpenCV 要勾 Add PATH (第二個)，裝在預設目錄
Setting-Compiler 裡，要把 OpenCV 的三個設定設好
(1) 重開 CodeBlocks
原本的檔案在 View Start Page
(2) 在 Search directories 加入2個目錄
1-1 Compiler C:\OpenCV2.1\include
1-2 Linker C:\OpenCV2.1\lib
(3) 在 Linker setting 裡，加入
cv210
cxcore210
highgui210

week14-2_alpha_blending
先用"s"存動作後再按"p"會自動播放剛剛的動作
複製week14-1變成week14-2_alpha_blending
改.cbp的檔名&開啟Notepad++做修改
開啟Excel檔!輸入一些資料，套用公式
alpha: =左邊座標/20
內插結果: =新的*alpha+舊的*(1-alpha)
