v1.1.1

This release fixed issue #4: Allow to set maxAge and IoUThreshold like this:

sortnode.SortNode(kMinHits, kMaxAge, kIoUThreshold, kMinConfidence);

The SortNode object can be initialize with 4 arguments in the following order:

• kMinHits: (int) Minimum number of hits before a bounding box was assigned a new track ID (should be 3)
• kMaxAge: (int) Maximum number of frames to keep alive a track without associated detections
• kIoUThreshold: (float between 0 and 1) Minimum IOU for match (should be 0.3)
• kMinConfidence: (float between 0 and 1) Bouding boxes with confidence score less than this value will be ignored

v1.1.0

This release fixed issue #2. Adding support for additional landmarks information for easier mapping.

The update method expect a single arguments that had a the format List[List[float]], which means a list of detected object in that frame. Each object will have the format: [x_top, y_top, width, height, confidence] or [x_top, y_top, width, height, confidence, landmark_x1, landmark_y1, ...] for additional landmark associated with each bounding box.

The update method will return a list of tracked object in the format List[Object], each object will have the following structure:

{
    bbox: List[(int) x_top, y_top, width, height],
    track_id: int,
    landmarks: List[(float) x1, y1, x2, y2, ..., x_n, y_n],
}
