HoughProbLineInit

Initializes the specification structure for line detection with the probabilistic Hough transform algorithm.

Syntax

IppStatus ippiHoughProbLineInit_8u32f_C1R(IppiSize roiSize, IppPointPolar delta, IppHintAlgorithm hint, IppiHoughProbSpec* pSpec);

Headers: ippcore.h, ippvm.h, ipps.h, ippi.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib, ippi.lib

roiSize: Size of the source image ROI, in pixels.
delta: Step of discretization (delta.rho - radial increment, delta.theta - angular increment).
hint: Suggests using specific code for calculations.
pSpec: Pointer to the IppiHoughProbSpec structure.

This function operates with ROI.

This function initializes the IppiHoughProbSpec specification structure that is required for the ippiHoughProbLine function.

For an example on how to use this function, see the example provided with the ippiHoughProbLine function description.

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error if pBufSize is `NULL`.
ippStsSizeErr	Indicates an error condition if roiSize or delta has a field with zero or negative value.
