Function Documentation

◆ dwParkNet_getDNNMetaData()

DW_API_PUBLIC dwStatus dwParkNet_getDNNMetaData ( dwDNNMetaData *  metaData,
dwParkNetHandle_t  obj 
)

Returns the DNN metadata.

Parameters
[out]metaDataPointer to metaData struct.
[in]objThe handle to ParkNet.
Returns
DW_SUCCESS, DW_INVALID_HANDLE, DW_BAD_CAST, DW_INVALID_ARGUMENT

◆ dwParkNet_getInputBlobSize()

DW_API_PUBLIC dwStatus dwParkNet_getInputBlobSize ( dwBlobSize *  blobSize,
dwParkNetHandle_t  obj 
)

Gets the size of the input blob.

Parameters
[out]blobSizesize of input blob.
[in]obj- handle for the Parknet object.
Returns
DW_SUCCESS, DW_INVALID_ARGUMENT

◆ dwParkNet_getOutputBlobSize()

DW_API_PUBLIC dwStatus dwParkNet_getOutputBlobSize ( dwBlobSize *  blobSize,
dwParkNetHandle_t  obj 
)

Gets the size of the output blob.

Parameters
[out]blobSizesize of output blob.
[in]obj- handle for the Parknet object.
Returns
DW_SUCCESS, DW_INVALID_ARGUMENT

◆ dwParkNet_initDefaultParams()

DW_API_PUBLIC dwStatus dwParkNet_initDefaultParams ( dwParkNetParams *  params,
dwContextHandle_t  ctx 
)

Initializes ParkNet parameters with default values.

Parameters
[out]paramsParkNet default parameters.
[in]ctxThe handle to the context.
Returns
DW_SUCCESS, DW_INVALID_ARGUMENT
Note
Default precision depends on the current GPU.

◆ dwParkNet_initialize()

DW_API_PUBLIC dwStatus dwParkNet_initialize ( dwParkNetHandle_t *  ParkNetHandle,
const dwParkNetParams *  ParkNetParams,
dwContextHandle_t  ctx 
)

Initializes ParkNet module.

Parameters
[out]ParkNetHandleA pointer to ParkNet handle to be initialized.
[in]ParkNetParamsParkNet parameters
[in]ctxThe handle to the context.
Returns
DW_SUCCESS, DW_INVALID_HANDLE, DW_BAD_CAST, DW_INVALID_ARGUMENT
Note
If ParkNet module is to be loaded on a non-default GPU Device, the initialization must take place after dwContext_selectGPUDevice.

◆ dwParkNet_release()

DW_API_PUBLIC dwStatus dwParkNet_release ( dwParkNetHandle_t  obj)

Releases the ParkNet module.

Parameters
[in]objThe handle to ParkNet.
Returns
DW_SUCCESS, DW_INVALID_HANDLE, DW_BAD_CAST
Note
This method renders the handle unusable.

◆ dwParkNet_reset()

DW_API_PUBLIC dwStatus dwParkNet_reset ( dwParkNetHandle_t  obj)

Resets ParkNet.

Parameters
[in]objHandle to ParkNet.
