FUNCTIONgapi_ot_track1
RETURN TYPEtuple_GArray_Rect_and_GArray_int_end__and_GArray_uint64_t_end__and_GArray_int
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Tracks objects with video frames. Overload of track(...) for frame as GFrame.

gapi_ot_track1(frame: GFrame, detected_rects: GArray_Rect, detected_class_labels: GArray_int, delta: number): tuple_GArray_Rect_and_GArray_int_end__and_GArray_uint64_t_end__and_GArray_int;
frame

Input frame.

detected_rects

Detected objects rectangles in the input frame.

detected_class_labels

Detected objects class labels in the input frame.

delta

Frame_delta_t Delta time between two consecutive tracking in seconds. The valid range is [0.005 ~ 0.5].

Returns

Tracking results of target objects. cv::GArraycv::Rect Array of rectangles for tracked objects. cv::GArray<int32_t> Array of detected objects labels. cv::GArray<uint64_t> Array of tracking IDs for objects. Numbering sequence starts from 1. The value 0 means the tracking ID of this object has not been assigned. cv::GArray<int> Array of tracking statuses for objects.
