Re: CvSobel

  Hello, Stefan!
   
  Try something like this:
   
  IplImage* src;
  IplImage* outra;
  IplImage* sobelImg;
   
  // load src
  outra = cvCreateImage( cvGetSize(src), IPL_DEPTH_16S, 1 );
  cvSobel( src, outra, 1, 1 );
  sobelImg = cvCreateImage( cvGetSize(src), IPL_DEPTH_8U, 1 );
  cvConvertScale( outra, sobelImg ); 
  cvNamedWindow( "3.Sobel", 1 );
  cvShowImage( "3.Sobel", sobelImg );
   
  With best regards,

  Hello,
could anyone explain me the usage of CVSobel? I Dont know, how I can compute 
the first derivatives respectively how I can use the result of CVSobel. If I 
compute the derivative manually, I get other values.

Thanks
Stefan
