Function Documentation

◆ dwRoadMarkNet_getClassLabel()

DW_API_PUBLIC dwStatus dwRoadMarkNet_getClassLabel	(	const char **	classLabel,
		dwRoadmarkType	roadmarkType,
		dwRoadMarkNetHandle_t	obj
	)

Returns the class label for a given class index.

Parameters

[out]	classLabel	Pointer to class label.
[in]	roadmarkType	Roadmark class for which class label is requested.
[in]	obj	The handle to RoadMarkNet.

Returns: DW_SUCCESS
DW_INVALID_HANDLE - If the given context handle is invalid,i.e. null or of wrong type
DW_BAD_CAST
DW_INVALID_ARGUMENT - If the given classLabel pointer is NULL

◆ dwRoadMarkNet_getDNNMetaData()

DW_API_PUBLIC dwStatus dwRoadMarkNet_getDNNMetaData	(	dwDNNMetaData *	metaData,
		dwRoadMarkNetHandle_t	obj
	)

Returns the DNN metadata.

Parameters

[out]	metaData	Pointer to metaData struct.
[in]	obj	Specifies the RoadMarkNet handle.

Returns: DW_SUCCESS
DW_INVALID_HANDLE - If the given context handle is invalid,i.e. null or of wrong type
DW_BAD_CAST
DW_INVALID_ARGUMENT - If the given metadata pointer is NULL

◆ dwRoadMarkNet_getInputBlobsize()

DW_API_PUBLIC dwStatus dwRoadMarkNet_getInputBlobsize	(	dwBlobSize *	inputBlobsize,
		dwRoadMarkNetHandle_t	obj
	)

Returns input blob size that RoadMarkNet expects.

Parameters

[out]	inputBlobsize	Input blob size.
[in]	obj	Specifies the RoadMarkNet handle.

Returns: DW_SUCCESS
DW_INVALID_HANDLE - If the given context handle is invalid,i.e. null or of wrong type
DW_BAD_CAST
DW_INVALID_ARGUMENT - if the given input blobsize pointer is NULL

◆ dwRoadMarkNet_initDefaultParams()

DW_API_PUBLIC dwStatus dwRoadMarkNet_initDefaultParams	(	dwRoadMarkNetParams *	roadMarkNetParams,
		dwContextHandle_t	ctx
	)

Initializes RoadMarkNet parameters with default values.

Parameters

[out]	roadMarkNetParams	RoadMarkNet parameters.
[in]	ctx	The handle to the context.

Returns: DW_SUCCESS
DW_INVALID_ARGUMENT - If the given params pointer is NULL

Note: Default precision depends on the current GPU.

◆ dwRoadMarkNet_initialize()

DW_API_PUBLIC dwStatus dwRoadMarkNet_initialize	(	dwRoadMarkNetHandle_t *	roadMarkNetHandle,
		const dwRoadMarkNetParams *	roadMarkNetParams,
		dwContextHandle_t	ctx
	)

Initializes RoadMarkNet module.

Parameters

[out]	roadMarkNetHandle	A pointer to RoadMarkNet handle to be initialized.
[in]	roadMarkNetParams	RoadMarkNet parameters.
[in]	ctx	The handle to the context.

Returns: DW_SUCCESS
DW_INVALID_ARGUMENT - If the given context handle is invalid, i.e null or of wrong type
DW_BAD_CAST
DW_INVALID_ARGUMENT - If the given roadMarkNet handle or roadMarkNetParams pointers are NULL

Note: If RoadMarkNet module is to be loaded on a non-default GPU Device, the initialization must take place after dwContext_selectGPUDevice.

◆ dwRoadMarkNet_release()

DW_API_PUBLIC dwStatus dwRoadMarkNet_release ( dwRoadMarkNetHandle_t obj )

Releases the RoadMarkNet module.

Parameters

[in] obj The handle to RoadMarkNet.

Returns: DW_SUCCESS
DW_INVALID_ARGUMENT - If the given handle is invalid,i.e. null or of wrong type
DW_BAD_CAST

Note: This method renders the handle unusable.

◆ dwRoadMarkNet_reset()

DW_API_PUBLIC dwStatus dwRoadMarkNet_reset ( dwRoadMarkNetHandle_t obj )

Resets RoadMarkNet.

Parameters

[in] obj Handle to RoadMarkNet.

Returns: DW_SUCCESS
DW_INVALID_ARGUMENT - If the given handle is invalid, i.e null or of wrong type
DW_BAD_CAST
