为了尊重原作，我没有修改代码，为了在我之前博文中配置好的MSVS2010中跑这个程序，我做了一些小修改，注意，算法是不变的。

代码如下：

#include 
    
     #include 
     
      #include 
      
       using namespace cv;using namespace std;double alpha; /**< Simple contrast control */int beta;  /**< Simple brightness control */int main( int argc, char** argv ){ /// Read image given by user Mat image = imread("lena.jpg");  /// matlab风格的初始化0值Mat对象 Mat new_image = Mat::zeros( image.size(), image.type() ); /// Initialize values std::cout<<" Basic Linear Transforms "<
       
        >alpha; std::cout<<"* Enter the beta value [0-100]: "; std::cin>>beta; /// Do the operation new_image(i,j) = alpha*image(i,j) + beta for( int y = 0; y < image.rows; y++ )    { for( int x = 0; x < image.cols; x++ )         { for( int c = 0; c < 3; c++ )              {      new_image.at
        
         (y,x)[c] =         saturate_cast
         
          ( alpha*( image.at
          
           (y,x)[c] ) + beta ); } } } /// Create Windows namedWindow("Original Image", 1); namedWindow("New Image", 1); /// Show stuff imshow("Original Image", image); imshow("New Image", new_image); /// Wait until user press some key waitKey(0); return 0;}
