opencv中cvPyrSegmentation出现问题了

[ogiso_pest]

运行学习opencv中的代码，但是出现了错误
提示窗口

Bad argument （OpenCV function failed）
in function cvPyrSegmentation ,c:\User\vp\opencv\src\cvPyrSegmentation.cpp 1870
谢谢了啊

   Right to use this code in any way you want without warrenty, support or any guarentee of it working.

改成这样就可以了，我已调试通过：
#include <stdio.h>
#include <cv.h>
#include <highgui.h>
#include <stdio.h>

void f(
IplImage* src,
IplImage* dst
) {
CvMemStorage* storage = cvCreateMemStorage(0);
CvSeq* comp = NULL;

cvPyrSegmentation( src, dst, storage, &comp, 4, 200, 50 );
int n_comp = comp->total;

for( int i=0; i<n_comp; i++ ) {
CvConnectedComp* cc = (CvConnectedComp*) cvGetSeqElem( comp, i );
// do_something_with( cc );
}
cvReleaseMemStorage( &storage );
}

int main(int argc, char** argv)
{

// Create a named window with a the name of the file.
cvNamedWindow( "201001071230101.jpg", 1 );
// Load the image from the given file name.
IplImage* src = cvLoadImage( "201001071230101.jpg" );
if(!src) { printf("Couldn't seem to Open %s, sorry\n",argv[1]); return -1;}
IplImage* dst = cvCreateImage( cvGetSize(src), src->depth, src->nChannels);
f( src, dst);

// Show the image in the named window
cvShowImage( "201001071230101.jpg", dst );

// Idle until the user hits the "Esc" key.
while( 1 ) { if( cvWaitKey( 100 ) == 27 ) break; }

// Clean up and don鈥檛 be piggies
cvDestroyWindow( "201001071230101.jpg" );
cvReleaseImage( &src );
cvReleaseImage( &dst );

return 0;

我按二楼的来，还是那个问题啊！！！
求指导

这个问题我也碰到过，这是因为cvPyrSegmentation这个函数对输入输出图像时有要求的，具体可以参考学习opencv这本书
