Method Detail

getName

@StdString
public BytePointer getName()

Description copied from class: Node

Retrieves nodes name

Overrides:

getName in class Node

inputTrackerFrame

@MemberGetter
 @ByRef
public Node.Input inputTrackerFrame()

Input ImgFrame message on which tracking will be performed. RGBp, BGRp, NV12, YUV420p types are supported. Default queue is non-blocking with size 4.

inputDetectionFrame

@MemberGetter
 @ByRef
public Node.Input inputDetectionFrame()

Input ImgFrame message on which object detection was performed. Default queue is non-blocking with size 4.

inputDetections

@MemberGetter
 @ByRef
public Node.Input inputDetections()

Input message with image detection from neural network. Default queue is non-blocking with size 4.

out

@MemberGetter
 @ByRef
public Node.Output out()

Outputs Tracklets message that carries object tracking results.

passthroughTrackerFrame

@MemberGetter
 @ByRef
public Node.Output passthroughTrackerFrame()

Passthrough ImgFrame message on which tracking was performed. Suitable for when input queue is set to non-blocking behavior.

passthroughDetectionFrame

@MemberGetter
 @ByRef
public Node.Output passthroughDetectionFrame()

Passthrough ImgFrame message on which object detection was performed. Suitable for when input queue is set to non-blocking behavior.

passthroughDetections

@MemberGetter
 @ByRef
public Node.Output passthroughDetections()

Passthrough image detections message from neural nework output. Suitable for when input queue is set to non-blocking behavior.

setTrackerThreshold

public void setTrackerThreshold(float threshold)
