ThresholdAdaptiveGaussGetBufferSize
Computes the size of the adaptive threshold specification structure and the size of the work buffer for adaptive thresholding with the Gaussian method.
Syntax
IppStatus ippiThresholdAdaptiveGaussGetBufferSize(IppiSize roiSize, IppiSize maskSize, IppDataType dataType, int numChannels, int* pSpecSize, int* pBufferSize);
Include Files

Domain Dependencies
Headers: ippcore.h, ippvm.h, ipps.h
Libraries: ippcore.lib, ippvm.lib, ipps.lib
Parameters
- roiSize
-
Size of the destination image ROI, in pixels.
- maskSize
-
Size of the kernel that is used to calculate a threshold level. Width and height of maskSize must be equal and odd.
- dataType
-
Data type of the source and destination images. Possible value is ipp8u.
- numChannels
-
Number of channels in the images. Possible value is 1.
- pSpecSize
-
Pointer to the size of the adaptive threshold specification structure.
- pBufferSize
-
Pointer to the size (in bytes) of the external work buffer.
Description
This function computes the size, in bytes, of the adaptive threshold specification structure and the size of the external work buffer needed for the ThresholdAdaptiveGauss function. The results are stored in pSpecSize and pBufferSize.
For an example on how to use this function, refer to the example provided with the ThresholdAdaptiveGauss function description.
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error.
- ippStsNullPtrErr
- Indicates an error when pSpecSize or pBufferSize is NULL.
- ippStsSizeErr
- Indicates an error when roiSize has a field with a zero or negative value.
- ippStsMaskSizeErr
- Indicates an error when maskSize has a field with a zero or negative value, or fields of maskSize are not equal.
- ippStsDataTypeErr
- Indicates an error when dataType has an illegal value.
- ippStsNumChannelsErr
- Indicates an error when numChannels has an illegal value.
