startTracking(at:within:sourceImage:sourceDisparity:)
Starts creating a detection track to track an object within the given bounds.
Declaration
func startTracking(at time: CMTime, within normalizedBounds: CGRect, sourceImage: CVPixelBuffer, sourceDisparity: CVPixelBuffer) -> BoolParameters
- time:
The presentation time of the first frame in the detection track.
- normalizedBounds:
The bounds of the object to track in normalized coordinates where (0.0, 0.0) is the upper-left corner, and (1.0, 1.0) is the lower-right.
- sourceImage:
The image buffer containing the image.
- sourceDisparity:
The disparity buffer containing depth information.
Return Value
A flag representing whether the object can be tracked.
Discussion
If you can track the object, the system adds a detection to the detection track you’re building.
