Function Documentation

pvaAlgosMogBackgroundSubtractorDeInit()

pvaAlgosError_t pvaAlgosMogBackgroundSubtractorDeInit

(

pvaAlgosMogBackgroundSubtractorContext_t *

mogContext

)

Frees the internal objects and the MogBackgroundSubtractorContext object.

Parameters

[in]

mogContext

The pointer to a pvaAlgosMogBackgroundSubtractorContext_t object that stores the internal parameters needed for Background subtractor

Returns

pvaAlgosError_t The completion status of the operation. Its value is pvaAlgosStatusSuccess if the operation is successful

pvaAlgosMogBackgroundSubtractorGetContext()

pvaAlgosError_t pvaAlgosMogBackgroundSubtractorGetContext

(

pvaAlgosMogBackgroundSubtractorContext_t *

mogContext

)

Initializes MogBackgroundSubtractorContext object and sends it back to the caller.

Parameters

[in]

mogContext

The pointer to a pvaAlgosMogBackgroundSubtractorContext_t object that stores the internal parameters needed for Background subtractor

Returns

pvaAlgosError_t The completion status of the operation. Its value is pvaAlgosStatusSuccess if the operation is successful

pvaAlgosMogBackgroundSubtractorInit()

pvaAlgosError_t pvaAlgosMogBackgroundSubtractorInit	(	pvaAlgosMogBackgroundSubtractorContext_t *	mogContext,
		pvaAlgosMogBackgroundSubtractorConfig_t *	mogParams
	)

Initializes the necessary values for the internal objects in pvaAlgosMogBackgroundSubtractorContext_t object.

Parameters

[in]	mogContext	The pointer to a pvaAlgosMogBackgroundSubtractorContext_t object that stores the internal parameters needed for Background subtractor
[in]	mogParams	The pointer to a pvaAlgosMogBackgroundSubtractorConfig_t object that stores the configuration parameters for Background subtractor

Returns

pvaAlgosError_t The completion status of the operation. Possible values are:

• pvaAlgosStatusSuccess if the operation was successful.
• pvaAlgosStatusInvalidParameter if the parameter is invalid.

pvaAlgosMogBackgroundSubtractorProcess()

pvaAlgosError_t pvaAlgosMogBackgroundSubtractorProcess	(	pvaAlgosMogBackgroundSubtractorContext_t *	mogContext,
		pvaAlgosMogBackgroundSubtractorIOBuffer_t *	mogBuffers,
		cupvaStream_t *	instanceStream,
		int	execTimeout
	)

Sets the I/O Buffers to the internal objects and runs the Background subtractor Algorithm.

Parameters

[in]	mogContext	The pointer to a pvaAlgosMogBackgroundSubtractorContext_t object that stores the internal parameters needed for Background subtractor
[in]	mogBuffers	The pointer to a pvaAlgosMogBackgroundSubtractorIOBuffer_t object that stores the I/O Buffers that change each frame
[in]	postFence	The pointer to a cupvaFence_t object needed for the synchronization across instructions sent to the PVA Engine
[in]	instanceStream	The pointer to a cupvaStream_t object needed to submit instructions to the PVA Engine

Returns

pvaAlgosError_t The completion status of the operation. Its value is pvaAlgosStatusSuccess if the operation is successful
