OpenCV錯誤：輸入參數的格式不匹配

Question

我不明白爲什麼我的程序不能在我的電腦上運行，而在學校電腦上工作正常！也許這是配置上的問題。我與Ubuntu 9.10的工作和OpenCV 2.2

這裏的最後一個版本的代碼：

#include <stdio.h> 
#include <cv.h> 
#include <highgui.h> 



int main (int argc, char *argv[]) 
{ 
    double a[9]={1,0,-1,2,0,-2,1,0,-1}; 
    double b[9]={1,2,1,0,0,0,-1,-2,-1}; 

    IplImage* img=cvLoadImage(argv[1], 0); 
    if(!img){ 
     printf("could not load image file: %s\n",argv[1]); 
     exit(0); 
    } 

    IplImage* dst=cvCreateImage(cvGetSize(img),IPL_DEPTH_64F,1); 
    IplImage* dst1=cvCreateImage(cvGetSize(img),IPL_DEPTH_64F,1); 
    IplImage* dst2=cvCreateImage(cvGetSize(img),IPL_DEPTH_64F,1); 
    IplImage* dst_f=cvCreateImage(cvGetSize(img),IPL_DEPTH_8U,1); 
    CvMat k1 = cvMat(3,3,CV_64FC1,a); 
    CvMat k2 = cvMat(3,3,CV_64FC1,b); 
    cvFilter2D(img ,dst1, &k1,cvPoint(-1,-1)); 
    cvFilter2D(img ,dst2, &k2,cvPoint(-1,-1)); 
    cvPow(dst1, dst1, 2.0); 
    cvPow(dst2, dst2, 2.0); 
    cvAdd(dst1, dst2, dst, NULL); 
    cvPow(dst, dst, 0.5); 
    cvConvertImage(dst,dst_f,CV_CVTIMG_FLIP); 
    cvThreshold(dst_f,dst_f,127,255,CV_THRESH_BINARY); 
    cvNamedWindow("mainWin", CV_WINDOW_AUTOSIZE); 
    cvMoveWindow("mainWin", 100, 100); 
    cvShowImage("mainWin",img); 
    cvNamedWindow("Sobel", CV_WINDOW_AUTOSIZE); 
    cvShowImage("Sobel",dst_f); 
    cvWaitKey(0); 
    cvReleaseImage(&img); 
    cvReleaseImage(&dst_f); 
    return 0; 
} 

這是運行

OpenCV ERROR: Formats of input arguments do not match() in function cvFilter2D, cvfilter.cpp(2617) Terminating the application... called from cvUnregisterType, cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, cxpersistence.cpp(4933) Terminating the application...

當終端返回請幫我理解這個問題。

Answer 1

您的錯誤是tjat您需要使用CvMat變量來存儲矩陣來存儲您的過濾器並將其應用到cvFilter 2D圖像中。

我給你2個樣本代碼來了解這個程序。

創建並初始化一個矩陣。用另一種選擇高通濾波的

double a[] = { 1, 2, 3, 4 
       5, 6, 7, 8, 
       9, 10, 11, 12 }; 

double b[] = { 1, 5, 9, 
       2, 6, 10, 
       3, 7, 11, 
       4, 8, 12 }; 
double c[9]; 
CvMat Ma, Mb, Mc ; 

cvInitMatHeader(&Ma, 3, 4, CV_64FC1, a); 
cvInitMatHeader(&Mb, 4, 3, CV_64FC1, b); 
cvInitMatHeader(&Mc, 3, 3, CV_64FC1, c); 

cvMatMulAdd(&Ma, &Mb, 0, &Mc); 
// c array now contains product of a(3x4) and b(4x3) matrices 

Answer 2

實施例到矩陣初始化

int main() 

{ *與CvMat內核= 0; IplImage * src = cvLoadImage（「chica.jpg」）; IpgImage * dst = cvCreateImage（cvGetSize（src），32,3）;

kernel = cvCreateMat(3, 3,CV_32FC1); 
cvSet2D(kernel, 0, 0, cvRealScalar(0)); 
cvSet2D(kernel, 0, 1, cvRealScalar(-1)); 
cvSet2D(kernel, 0, 2, cvRealScalar(0)); 
cvSet2D(kernel, 1, 0, cvRealScalar(-1)); 
cvSet2D(kernel, 1, 1, cvRealScalar(5)); 
cvSet2D(kernel, 1, 2, cvRealScalar(-1)); 
cvSet2D(kernel, 2, 0, cvRealScalar(0)); 
cvSet2D(kernel, 2, 1, cvRealScalar(-1)); 
cvSet2D(kernel, 2, 2, cvRealScalar(0)); 

// Matriz utilizada para el filtrado paso alto 
// 0 -1 0 
// -1 5 -1 
// 0 -1 0 

cvFilter2D(src, dst, kernel, cvPoint(-1,-1)); 

cvNamedWindow("Image Original",1); 
cvShowImage("Image Original",src); 

cvNamedWindow("Image Filtrada",1); 
cvShowImage("Image Filtrada",src); 

cvWaitKey(0); 
cvReleaseImage(&src); 
cvReleaseImage(&dst); 

cvDestroyWindow("Image Original"); 
cvDestroyWindow("Image Filtrada"); 
// release the image 


return 0; 

}
