konfigurasi opencv 2.4.9 pada visual studio 2012

1. Download VS 2012 (vc11)
2. Download Opencv (2.4.9)
3. Extract Opencv
4. (visual Studio) Buat Win32(C++) Console Application
5. (Opencv + Visual stuio)  Klik kanan menu project --> Propertis
6. (Opencv + Visual stuio)  Pilih Configuration Manager --> Tambahkan x64 jika 64bit, jika 32bit sdh secara default

 /// We use the alpha provided by the user if it is between 0 and 1
 if( input >= 0.0 && input <= 1.0 )
   { alpha = input; }

 /// Read image ( same size, same type )
 src1 = imread("foto.jpg");
