i am using fuction ippiConvValid in the next code
Conv(HGLOBAL& phDIBS, HGLOBAL& phDIBD)
{// where phDIBS is 32bpp bitmap
lpbi = (LPBITMAPINFOHEADER)phDIBS;
sizeS.height = lpbi->biHeight;
sizeS.width = lpbi->biWidth;
// pointer on asource
Ipp32f* pS = (Ipp32f*)GlobalLock(phDIBS);
// pointer on adest
Ipp32f* pD = (Ipp32f*)GlobalLock(phDIBD);
// malloc mem for 3x3 kernel
HGLOBAL hKern = ::GlobalAlloc(GMEM_FIXED | GMEM_ZEROINIT,
sizeof(Ipp32f)*9);
Ipp32f* pKernel = (Ipp32f*)GlobalLock(hKern);
sizeK.height = 3;
sizeK.width = 3;
int stepBytes;Ipp32f arr[9] = {0,0,0,0,1,0,0,0,0};
or(int y = 0; y < GlobalSize(pKernel)/sizeof(Ipp32f); y++)
{
*(pKernel+y) = arr;
}
ippiConvValid_32f_C3R(
(Ipp32f*)(pS+(
sizeof(BITMAPINFOHEADER)/sizeof(Ipp32f))),sizeS.width * sizeof(Ipp32f) , sizeS,(Ipp32f*)pKernel, 3 * sizeof(Ipp32f), sizeK,
(Ipp32f*)pD,sizeS.width *
sizeof(Ipp32f));
....
}
programm are broken in ippiConvValid
May be trable in ipp libs
