I made a simple script using the ErodeBorder function in IPP, and I want to use ippiErode_1u_C1R_L. I am having trouble using ippiErode_1u_C1R_L I keep getting an AccessViolation Exception. First script shows a functioning code, second script shows an attempt to use ippiErode_1u_C1R_L.

Working Code:

int width = 1600;
int height = 594;
int binSize = 118800;
int binStep = ceil(width / 8);
IppiSize roi = { width, height };

Ipp8u* workBin = (Ipp8u*)ippsMalloc_8u(binSize);
Ipp8u* defectMask = (Ipp8u*)ippsMalloc_8u(binSize);
Ipp8u* origBin = GetMask(); //Same size as workBin

Ipp8u mask[9] = { 1, 1, 1,
                  1, 0, 1,
                  1, 1, 1 };

IppiSize maskSize = { 3, 3 };
int pSpecSize = 0, pBufferSize = 0;

ippiMorphologyBorderGetSize_1u_C1R(roi, maskSize, &pSpecSize, &pBufferSize);
Ipp8u* pBuffer = (Ipp8u*)ippsMalloc_8u(pBufferSize);
IppiMorphState* pSpec = (IppiMorphState*)ippsMalloc_8u(pSpecSize);
ippiMorphologyBorderInit_1u_C1R(roi, mask, maskSize, pSpec, pBuffer);

ippiErodeBorder_1u_C1R(origBin, binStep, 0, workBin, binStep, 0, roi, ippBorderRepl, 0, pSpec, pBuffer);
ippiErodeBorder_1u_C1R(workBin, binStep, 0, defectMask, binStep, 0, roi, ippBorderRepl, 0, pSpec, pBuffer);
ippiErodeBorder_1u_C1R(defectMask, binStep, 0, workBin, binStep, 0, roi, ippBorderRepl, 0, pSpec, pBuffer);
ippiErodeBorder_1u_C1R(workBin, binStep, 0, defectMask, binStep, 0, roi, ippBorderRepl, 0, pSpec, pBuffer);

Throws Exception when calling ippiErode_1u_C1R_L():

int width = 1600;
int height = 594;
int binSize = 118800; 
int binStep = ceil(width / 8);

IppiSizeL roi_L = { width, height };
Ipp8u* workBin = (Ipp8u*)ippsMalloc_8u(binSize);
Ipp8u* defectMask = (Ipp8u*)ippsMalloc_8u(binSize);
Ipp8u* origBin = GetMask(); //Same size as workBin

Ipp8u mask[9] = { 1, 1, 1,
                  1, 0, 1,
                  1, 1, 1 };

IppiSizeL maskSize = { 3, 3 };
IppSizeL pSpecSize = 0, pBufferSize = 0;

ippiErodeGetBufferSize_L(roi_L, maskSize, ipp1u, 1, &pBufferSize);
ippiErodeGetSpecSize_L(roi_L, maskSize, &pSpecSize);
Ipp8u* pBuffer = (Ipp8u*)ippsMalloc_8u_L(pBufferSize);
IppiMorphStateL* pSpec = (IppiMorphStateL*)ippsMalloc_8u_L(pSpecSize);
IppStatus initSizeStat = ippiErodeInit_L(roi_L, mask, maskSize, pSpec);

ippiErode_1u_C1R_L(origBin, binStep, 0, workBin, binStep, 0, roi_L, ippBorderRepl, 0, pSpec, pBuffer);

  • It could be a bug in IPP. Check [here](https://community.intel.com/t5/Intel-Integrated-Performance/ippiErode-1u-C1R-L-minimum-example-crashing/td-p/1170156). What IPP version are you using? If it's not the same issue, please post a code sample that we can build and execute (with `#include` and `main()`... post input an image if required). – Rotem Sep 23 '22 at 21:24
