Hi, I'm having some problems with ippiMorphOpenBorder_8u_C1R.
#include <stdio.h>
#include<Windows.h>
#include "ipp.h"
int main(){
IppiSize roiSize = {16, 5 };
IppiSize maskSize = { 4, 4 };
int iSpecSize, iBufferSize;
ippiMorphAdvGetSize_8u_C1R(roiSize, maskSize, &iSpecSize, &iBufferSize);
IppiMorphAdvState *pSpec = (IppiMorphAdvState*)ippsMalloc_8u(iSpecSize);
Ipp8u *pBuffer = ippsMalloc_8u(iBufferSize);
Ipp8u pMask[4*4] = { 1,0,0,1,0,1,1,0,1,1,1,0,0,1,1,1};
ippiMorphAdvInit_8u_C1R(roiSize, pMask, maskSize, pSpec, pBuffer);
Ipp8u pSrc[80] = { 10, 126, 83, 244, 162, 22, 183, 137, 224, 163, 114, 112, 42, 13, 160, 225,
39, 106, 206, 197, 105, 21, 189, 110, 79, 0, 99, 134, 41, 75, 51, 69,
158, 21, 158, 231, 75, 146, 218, 94, 173, 93, 226, 68, 65, 16, 190, 19,
233, 19, 4, 152, 146, 177, 159, 165, 20, 113, 207, 7, 89, 163, 113, 183,
194, 57, 129, 85, 198, 216, 221, 209, 221, 47, 75, 108, 156, 136, 190, 223
};
Ipp8u pDst[80] = { 0 };
IppStatus sts = ippiMorphOpenBorder_8u_C1R(pSrc, 16, pDst, 16, roiSize, ippBorderRepl, 0, pSpec, pBuffer);
for (int i = 0; i < 5; i++){
for (int j = 0; j < 16; j++){
printf("%d ", pDst[i * 16 + j]);
}
printf("\n");
}
printf("\n");
printf("\n");
printf("%d",sts);
system("pause");
}
Based on the results of my previous use of ErodeBorder_8u_C1R and DilateBorder_8u_C1R, I think when the mask is 4x4, it will fill 5x5. But the result of MorphOpenBorder_8u_C1R was different from what I thought.
Actual results:
| 10 | 75 | 75 | 75 | 75 | 22 | 79 | 79 | 79 | 79 | 13 | 16 | 16 | 13 | 19 | 19 |
| 19 | 75 | 75 | 75 | 105 | 22 | 79 | 105 | 79 | 79 | 20 | 20 | 16 | 19 | 19 | 19 |
| 19 | 19 | 85 | 85 | 75 | 146 | 105 | 105 | 146 | 79 | 20 | 68 | 19 | 16 | 68 | 19 |
| 57 | 19 | 19 | 85 | 146 | 105 | 146 | 146 | 146 | 47 | 75 | 47 | 89 | 136 | 113 | 113 |
| 57 | 57 | 85 | 85 | 146 | 146 | 146 | 146 | 47 | 47 | 75 | 75 | 89 | 136 | 136 | 136 |
I think:
| 10 | 75 | 75 | 75 | 75 | 22 | 79 | 79 | 79 | 79 | 13 | 16 | 16 | 13 | 19 | 19 |
| 19 | 75 | 75 | 75 | 105 | 22 | 79 | 105 | 79 | 79 | 20 | 20 | 16 | 19 | 19 | 19 |
| 19 | 19 | 85 | 85 | 75 | 146 | 105 | 79 | 146 | 79 | 20 | 68 | 19 | 16 | 68 | 19 |
| 57 | 19 | 4 | 85 | 146 | 105 | 146 | 146 | 20 | 47 | 75 | 7 | 89 | 136 | 113 | 113 |
| 57 | 57 | 85 | 85 | 146 | 146 | 146 | 146 | 47 | 47 | 75 | 75 | 89 | 136 | 136 | 136 |
So I'm confused if the mask is 4x4 and what the correct result should be and how it should be handled.
Thank you.

Hello,
Thanks for your attention.
There is an issue in advanced morphology (Open, Close, etc.) for even-sized kernels. We have already fixed it.
Please use odd-size kennel for your case. For your sample, we re-write it as below, it works well now. And it demonstrates that ippiMorphOpenBorder_8u_C1R has same results as ErodeBorder_8u_C1R + DilateBorder_8u_C1R

Hi，
Thank you for your reply. I'm sorry I just saw it today. Then may I ask whether the revised version has been released? Can I download it?
