Parameters
- dataType
- Data type of the source image. Possible values:ipp32f,ipp32s.
- roiSize
- Maximal size of the source image ROI, in pixels.
- pNum
- Pointer to the array of Haar classifier lengths.
- length
- Number of classifiers in the stage.
- pSize
- Pointer to the size of Haar classifier structure.
Description
This function operates with ROI (see
Regions of Interest in Intel IPP
).
This function computes the size of the
pState
structure that is required to calculate the sequence of Haar classifiers - classification stage. The
i
-th classifier in the stage has
pNum[i]
rectangular features.
The length of the
pThreshold
,
pVal1
, and
pVal2
vectors used in the
ippiHaarClassifierInit
function is equal to
length
.
The length of the
pFeature
and
pWeight
vectors is equal to:
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error when any of the specified pointers isNULL.
- ippStsSizeErr
- Indicates an error when:
- lengthor one of thepNum[i]values is less than, or equal to zero
- roiSizehas a field with a zero or negative value
- ippStsBadArgErr
- Indicates an error when one of the features is defined incorrectly.
- ippStsDataTypeErr
- Indicates an error whendataTypehas an illegal value.
