| void NvMOTMF_DeInit | ( | NvMOTMFContextHandle | contextHandle | ) |
Deinitializes fusion context.
The specified context is retired and may not be used again.
| contextHandle | The handle for the fusion context to be retired. |
| NvMOTMFStatus NvMOTMF_Init | ( | NvMOTMFConfig * | pConfigIn, |
| NvMOTMFContextHandle * | pContextHandle, | ||
| NvMOTMFConfigResponse * | pConfigResponse | ||
| ) |
Initializes the fusion context.
If successful, the context is configured as specified by pConfigIn.
| [in] | pConfigIn | A pointer to to a structure specifying the configuration. |
| [out] | pContextHandle | A pointer to a handle for the fusion context. The fusion context is created and owned by the fusion module. The returned context handle must be included in all subsequent calls for the specified stream. |
| [out] | pConfigResponse | A pointer to a structure that describes the operation's status. |
| NvMOTMFStatus NvMOTMF_Process | ( | NvMOTMFContextHandle | contextHandle, |
| NvMOTMFTrackedObjMeta * | pVideoChunk, | ||
| NvMOTMFObjectIdMap & | ipOpObjectIdMap | ||
| ) |
Processes a video chunk.
Given a context and a video chunk metadata, processes the metadata chunk. Once processed, each chunk becomes part of the history and will be used for processing all the future video chunks
| [in] | contextHandle | A context handle obtained from NvMOTInit(). |
| [in] | pVideoChunk | A pointer to the metadata of the chunk to be processed. |
| [out] | ipOpObjectIdMap | Reference to a map to return input object id to output object id mapping |
| NvMOTMFStatus NvMOTMF_Query | ( | NvMOTMFQuery * | pQuery | ) |
Query metadata fusion lib capabilities and requirements.
Answer query for this metadata fusion lib's capabilities and requirements.
| [out] | pQuery | A pointer to a query structure to be filled by the library. |
| NvMOTMFStatus NvMOTMF_RetrieveFusedData | ( | NvMOTMFContextHandle | contextHandle, |
| NvMOTMFTrackerFusedData * | pTrackerMiscData, | ||
| bool | eos | ||
| ) |
Retrieve the fused data.
Given a context retrieve the fused tracklets The fused tracklets are returned in "pFusedTracksStream" If eos = false : only the terminated tracklets are returned If eos = true, all the active tracklets are terminated and returned
| [in] | contextHandle | The context handle obtained from NvMOTInit() |
| [out] | pTrackerMiscData | Misc data from low level tracker that contains the fused tracklet data in pFusedTracksStream |
