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.
