最近这两天一直在研究命令行参数的编译，现代吗如下：

#include <highgui.h>
#include <math.h>
#include <cv.h>
 
IplImage *Igray = 0, *It = 0, *Iat;
 
int main( int 
argc, char** argv )
{
    //输入命令行
    double 
threshold = (double)atof( argv[1] ); //convert string to double
    int 
threshold_type = atoi( argv[2] ) ? CV_THRESH_BINARY : CV_THRESH_BINARY_INV;
    int 
adaptive_method = atoi( argv[3] ) ? CV_ADAPTIVE_THRESH_MEAN_C : CV_ADAPTIVE_THRESH_GAUSSIAN_C;
    int 
block_size = atoi( argv[4] );
    double 
offset = (double)atof( argv[5] );
    //加载灰度图
    if( ( Igray = cvLoadImage( argv[6], CV_LOAD_IMAGE_GRAYSCALE ) ) == 0 )
    {
        return 
-1;
    }
    //创建同样大小8位灰度图用于输出
    It = cvCreateImage( cvSize( Igray -> width, Igray -> height ), IPL_DEPTH_8U, 1 ); //单通道8位灰度图
    Iat = cvCreateImage( cvSize( Igray -> width, Igray -> height ), IPL_DEPTH_8U, 1 );
    //阈值化
    cvThreshold( Igray, It, threshold, 255, threshold_type );
    cvAdaptiveThreshold( Igray, Iat, 255, adaptive_method, threshold_type, block_size, offset );
    //命名窗体输出
    cvNamedWindow( "Raw", 1 );
    cvNamedWindow( "Threshold", 1 );
    cvNamedWindow( "Adaptive Threshold", 1 );
    cvShowImage( "Raw", Igray );
    cvShowImage( "Threshold", It );
    cvShowImage( "Adaptive Threshold", Iat );
    cvWaitKey(0);
    //回收内存
    cvReleaseImage( &Igray );
    cvReleaseImage( &It );
    cvReleaseImage( &Iat );
    cvDestroyWindow( "Raw" 
);
    cvDestroyWindow( "Threshold" 
);
    cvDestroyWindow( "Adaptive Threshold" 
);
 
    return 
0;
}
