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.
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.
