.Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance in bytes between starts of consecutive lines in the source image.
- pSrcDst
- Pointer to the decreased and reconstructed image ROI.
- srcDstStep
- Distance in bytes between starts of consecutive lines in the decreased and reconstructed image.
- roiSize
- Size of the source and destination image ROI.
- norm
- Type of norm to form the mask for dilation; the following values are possible:
- ippiNormInf
- Infinity norm (8-connectivity, 3x3 rectangular mask).
- ippiNormL1
- L1 norm (4-connectivity, 3x3 cross mask).
- pBuf
- Pointer to the buffer.
Description
This function operates with ROI (see Regions of Interest
in Intel IPP).
This function performs morphological reconstruction of
the increased source image by erosion [Vincent93]. The operation is performed in
the working buffer whose size should be computed using the function
MorphReconstructGetBufferSize
beforehand.This operation enables detection of the regional
minimums that can be used as markers for successive watershed
segmentation.
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error condition if one of the specified pointers isNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSizehas a field with a zero or negative value.
- ippStsStepErr
- Indicates an error condition ifsrcSteporsrcDstStepis less thanroiSize.width*<pixelSize>.
- ippStsNotEvenStepErr
- Indicates an error condition if one of the step values is not divisible by 4 for floating-point images.
- ippStsBadArgErr
- Indicates an error condition ifnormhas an illegal value.
