Parameters
- 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. Possible values for the hint parameter are described in IppHintAlgorithm enum Type.
- pSpec
-
Pointer to the IppiHoughProbSpec structure.
Description
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.
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 zero or negative value. |
