Parameters
roi
Size of the source image ROI, in pixels.
maxNGauss
Maximal size of the Gaussian mixture components.
pSpecSize
Pointer to the size of the
IppFGMMSpec_8u_C3R
structure.
Description
This function operates with ROI.
This function computes the size of the
IppFGMMSpec_8u_C3R
structure for the
FGMMForeground
and
FGMMBackground
functions.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when
pSpecSize
is
NULL
.
ippStsSizeErr
Indicates an error when
roi
is less than, or equal to zero.
ippStsBadArgErr
Indicates an error when
maxNumGauss
is less than, or equal to zero.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
