Parameters
- kernelSize
- Size of the rectangular kernel in pixels.
- dstRoiSize
- Maximal size of the destination image ROI (in pixels).
- dataType
- Data type of the source image. Possible values areipp8u,ipp16u,ipp16s,ipp32f, oripp64f.
- kernelType
- Data type of the filter kernel. Possible values areipp16s,ipp32f, oripp64f.
- numChannels
- Number of channels in the image. Possible values are 1, 3, or 4.
- pSpecSize
- Pointer to the size of the filter specification structure.
- pBufferSize
- Pointer to the size of the work buffer required for filtering.
Description
This function operates with ROI.
This function computes the size of the filter specification
structure
pSpec
and the
size of the buffer required for filtering operations. Call this function before
using the ippiFilterBorderInit
function.Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error when one of the specified pointers isNULL.
- ippStsSizeErr
- Indicates an error whenkernelSizehas a field with a zero or negative value, or ifdstRoiSizeis less than 1.
- ippStsDataTypeErr
- Indicates an error whendataTypeorkernelTypehas an illegal value.
- ippStsChannelErr
- Indicates an error whennumChannelshas an illegal value.
