我正在使用cvCreateSeq函數在opencv中創建序列，而調試時會發生異常，例如“未處理的異常在0x7c812afb”。我使用C語言進行編碼，并且IDE是Visual C ++ 2010 Express Edition。

誰能告訴我為什么發生此異常。

謝謝，

代碼是：-

void main()

{

char * file = "D:\\testImage.jpg";

temp(file);

}

void computeCococlust(char * filepath)

{

CvMemStorage * storageContour = NULL;

CvSeq * first_contour = NULL;

IplImage * iOriginal = NULL;

/*Load the image*/

iOriginal = cvLoadImage(filepath,CV_LOAD_IMAGE_UNCHANGED);

/*Load a Grayscale image*/

IplImage * iGray = cvLoadImage(filepath,CV_LOAD_IMAGE_GRAYSCALE);

/*Show original image in a window named 'Original Image'*/

fnShowImageInWindow("Original Image",iOriginal);

/*Show graylevel image in a window named 'GrayLevel Image'*/

fnShowImageInWindow("GrayLevel Image",iGray);

fnReleasingMemoryOfWindow("GrayLevel Image",iGray);

/*------Getting single channel image as red green blue from RGB iOriginal----------*/

IplImage *iRed = cvCreateImage(cvGetSize(iOriginal), iOriginal->depth, 1);

IplImage *iGreen = cvCreateImage(cvGetSize(iOriginal), iOriginal->depth, 1);

IplImage *iBlue = cvCreateImage(cvGetSize(iOriginal), iOriginal->depth, 1);

cvSplit(iOriginal, iBlue, iGreen, iRed, NULL);

/*Show iRed,iGreen,iBlue in window*/

fnShowImageInWindow("Red Component Image",iRed);

fnShowImageInWindow("Green Component Image",iGreen);

fnShowImageInWindow("Blue Component Image",iBlue);

/*---------------------------------------------------------------------------------*/

/*--------Perform canny edge detection--------------------------------------------*/

/*For Red Component*/

IplImage * eRed = cvCreateImage(cvGetSize(iRed),iRed->depth,1);

cvCanny(iRed,eRed,10,100,3);

/*For Green Component*/

IplImage * eGreen = cvCreateImage(cvGetSize(iGreen),iGreen->depth,1);

cvCanny(iGreen,eGreen,10,100,3);

/*For Blue Component*/

IplImage * eBlue = cvCreateImage(cvGetSize(iBlue),iBlue->depth,1);

int numCountour = cvFindContours(iUnionImage,storageContour,&first_contour,sizeof(CvContour),CV_RETR_CCOMP,CV_CHAIN_APPROX_NONE);

printf("Total countours detected %d",numCountour);

CvMemStorage * storage = cvCreateMemStorage(0);

/*-------------------------------------------------------------------------------*/

/*----Smoothing the contour------------------------------------------------------*/

for(CvSeq * seqSmooth = first_contour;seqSmooth!=NULL;seqSmooth = seqSmooth->h_next)

{

{

CvPoint newPoint = cvPoint((ps1->x + ps2->x + ps3->x + ps4->x + ps5->x)/5,(ps1->y + ps2->y + ps3->y + ps4->y + ps5->y)/5);

cvSeqPush(newSeq,&newPoint);

}

if(storageContour->bottom->prev != NULL)

{

CvMemBlock * oldNext = storageContour->bottom->next;

CvMemBlock * oldPrev = storageContour->bottom->prev;

storageContour->bottom = newSeq->storage->bottom;

storageContour->bottom->next = oldNext;

storageContour->bottom->prev = oldPrev;

}

else

{

CvMemBlock * oldNext = storageContour->bottom->next;

storageContour->bottom = newSeq->storage->bottom;

}

}
