NvDsInferObjectDetectionInfo
Holds information about one parsed object from a detector's output.
Definition: nvdsinfer.h:140
NvDsInferDBScanClusteringParams
Holds object clustering parameters required by DBSCAN.
Definition: nvdsinfer_dbscan.h:47
NvDsInferDBScanCreate
NvDsInferDBScanHandle NvDsInferDBScanCreate()
Creates a new DBScan object clustering context.
NvDsInferDBScanCluster
void NvDsInferDBScanCluster(NvDsInferDBScanHandle handle, NvDsInferDBScanClusteringParams *params, NvDsInferObjectDetectionInfo *objects, size_t *numObjects)
Clusters an array of objects in place using specified clustering parameters.
NvDsInferDBScanClusteringParams::thresholdATHR
float thresholdATHR
Holds the area-to-hit ratio threshold.
Definition: nvdsinfer_dbscan.h:55
nvdsinfer.h
NVIDIA DeepStream inference specifications
NvDsInferDBScanDestroy
void NvDsInferDBScanDestroy(NvDsInferDBScanHandle handle)

NvDsInferDBScanHandle
struct NvDsInferDBScan * NvDsInferDBScanHandle
Holds an opaque DBScan clustering context handle.
Definition: nvdsinfer_dbscan.h:44
NvDsInferDBScanClusteringParams::minScore
float minScore
Holds the sum of neighborhood confidence thresholds.
