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
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. |
