Typedefs
typedef struct dwObjectTrackerObject *	dwObjectTrackerHandle_t
	Handle to an object tracker. More...

Functions
DW_API_PUBLIC dwStatus	dwObjectTracker_boxTrackHost (dwObject *trackedDetections, size_t *numTrackedDetections, const dwObject *previousDetections, size_t numPreviousDetections, uint32_t classIdx, dwObjectTrackerHandle_t obj)
	Tracks objects in previousDetections based on the tracked features by previously called dwObjectTracker_featureTrackDeviceAsync. More...
DW_API_PUBLIC dwStatus	dwObjectTracker_boxTrackHostExternalFeatures (dwObject *trackedDetections, size_t *numTrackedDetections, const dwObject *previousDetections, size_t numPreviousDetections, const dwFeatureListPointers *featureList, uint32_t maxFeatureCount, uint32_t historyCapacity, uint32_t currentTimeIdx, uint32_t classIdx, dwObjectTrackerHandle_t obj)
	This function enables tracking of objects using already extracted features from the previous and current frame. More...
DW_API_PUBLIC dwStatus	dwObjectTracker_featureTrackDeviceAsync (const dwImageCUDA *image, dwObjectTrackerHandle_t obj)
	Tracks the features from a previously given image to the current image. More...
DW_API_PUBLIC dwStatus	dwObjectTracker_getCUDAStream (cudaStream_t *stream, dwObjectTrackerHandle_t obj)
	Gets the CUDA stream used. More...
DW_API_PUBLIC dwStatus	dwObjectTracker_initDefaultParams (dwObjectFeatureTrackerParams *featureTrackerParams, dwObjectTrackerParams *objectTrackerParamsArray, uint32_t numClasses)
	Initializes ObjectTracker parameters with default values. More...
DW_API_PUBLIC dwStatus	dwObjectTracker_initialize (dwObjectTrackerHandle_t *obj, dwContextHandle_t ctx, const dwImageProperties *imageProperties, const dwObjectFeatureTrackerParams *featureTrackerParams, const dwObjectTrackerParams *objectTrackerParamsArray, uint32_t numClasses)
	Initializes the ObjectTracker module. More...
DW_API_PUBLIC dwStatus	dwObjectTracker_release (dwObjectTrackerHandle_t *obj)
	Releases the ObjectTracker module. More...
DW_API_PUBLIC dwStatus	dwObjectTracker_reset (dwObjectTrackerHandle_t obj)
	Resets the ObjectTracker. More...
DW_API_PUBLIC dwStatus	dwObjectTracker_setCUDAStream (cudaStream_t stream, dwObjectTrackerHandle_t obj)
	Sets the CUDA stream used. More...
