FGMMInit

Initializes the state structure for the Gaussian mixture model foreground/background subtraction.

Syntax

IppStatus ippiFGMMInit_8u_C3R(IppiSize roi, int maxNGauss, IppFGMModel* pModel, IppFGMMState_8u_C3R* pState);

Headers: ippcore.h, ippvm.h, ipps.h, ippi.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib, ippi.lib

roi: Size of the source image ROI, in pixels.
maxNGauss: Maximal size of the Gaussian mixture components.
pModel: Pointer to the IppFGMModel structure containing parameters for the model. If pModel is NULL, the default parameters are applied.
pState: Pointer to the IppFGMMState_8u_C3R state structure.

This function operates with ROI.

This function initializes the IppFGMMState_8u_C3R state structure for the FGMMForeground and FGMMBackground functions.

Before using this function, you need to compute the size of the state structure using the FGMMGetBufferSize function.

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when pModel or pState is `NULL`.
ippStsSizeErr	Indicates an error when roi is less than, or equal to zero.
ippStsBadArgErr	Indicates an error when maxNGauss is less than, or equal to zero.
