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);

Include Files

ippcv.h

Domain Dependencies

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

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

Parameters

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.

Description

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.

Return Values

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.
