Problème avec cvPreWarpImage

Bonjour à tous,

j'aimerais expérimenter l'image morphing avec opencv, voici un bout de code que j'ai concocté mais arrivé à cvPreWarpImage le programme plante avec en guise d'erreur:

Citation:

Unhandled exception at 0x00b66cfd (cv100d.dll) in morphing.exe: 0xC0000005: Access violation writing location 0x01e3a000.

et en mode debug j'arrive à ce code:

cvSampleLine( const void* img, CvPoint pt1, CvPoint pt2,
              void* _buffer, int connectivity )
{
    ... //ligne 52 du fichier
    pix_size = CV_ELEM_SIZE(mat->type);
    for( i = 0; i < count; i++ )
    {
        CV_MEMCPY_AUTO( buffer, iterator.ptr, pix_size ); //////ICI PLANTAGE
        buffer += pix_size;
        CV_NEXT_LINE_POINT( iterator );
    }
    ...
}

qui est contenu dans le fichier cvsamplers.cpp

Quelqu'un aurait-il une idée d'où vient cette erreur?
Merci beaucoup!
