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 is NULL.
ippStsSizeErr	Indicates an error when: length or one of the pNum[i] values is less than, or equal to zero roiSize has a field with a zero or negative value
ippStsBadArgErr	Indicates an error when one of the features is defined incorrectly.
ippStsDataTypeErr	Indicates an error when dataType has an illegal value.
