HoughProbLineGetSize

Computes the size of the working buffer and spec structure for line detection with the probabilistic Hough transform algorithm.

Syntax

IppStatus ippiHoughProbLineGetSize_8u_C1R(IppiSize roiSize, IppPointPolar delta, int* pSpecSize, int* pBufSize);

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).
pSpecSize: Size of the IppiHoughProbSpec structure.
pBufSize: Pointer to the size of the working buffer.

This function operates with ROI.

This function computes the size of the temporary working buffer and the IppiHoughProbSpec specification structure 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 a zero or negative value.
