ippiFilterBox

[sohrab_ali]

Hi

I am trying to use ippiFilterBox but i am not getting the right results ,if some onecan help me with my this code

Ipp8u src[5][5] =
{
{2,4,6,8,10},
{1,1,1,1,1},
{1,1,1,1,1},
{1,1,1,1,1},
{1,1,1,1,1}
};

Ipp8u dst[5][5] =
{
{0,0,0,0,0},
{0,0,0,0,0},
{0,0,0,0,0},
{0,0,0,0,0},
{0,0,0,0,0}
};

IppiSize srcRoiSize;
srcRoiSize.width=5;
srcRoiSize.height=5;
int srcStep=5;

IppiSize dstRoiSize;
dstRoiSize.width=5;
dstRoiSize.height=5;
int dstStep=5;

IppiSize maskSize;
maskSize.width=3;
maskSize.height=3;

IppiPoint anchor;
anchor.x=1;
anchor.y=1;

Ipp8u temp[7][7];
Ipp8u value=1;
IppiSize tempRoiSize;
tempRoiSize.width=7;
tempRoiSize.height=7;

int tempStep=7;

IppStatus Status=ippiCopyConstBorder_8u_C1R((Ipp8u*)src,srcStep,srcRoiSize,(Ipp8u*)temp,tempStep,tempRoiSize, 1, 1, value);

Status=ippiFilterBox_8u_C1R((Ipp8u*)temp,tempStep,(Ipp8u*)dst, dstStep,dstRoiSize, maskSize,anchor);

I think i have to shift the temp but how....? and in this case if i shift the temp by1 byte it gets right results.

Hi, our expert answer that you should do

Code:

Status = ippiFilterBox_8u_C1R(
  (temp + anchor.x + anchor.y * tempStep),
  tempStep,
  (Ipp8u*)dst,
  dstStep,
  dstRoiSize,
  maskSize,
  anchor);

Regards,

Vladimir
