It has the following contents: fx 0 ox 0 fy oy 0 0 1 fx and fy are the focal length in pixels. For square pixels, they will have the same value. ox and oy are the coordinates of the principal point. The origin is the upper left of the frame. @note When using a CMSampleBuffer as an input and that sample buffer has camera intrinsics attached to it, Vision will use the camera intrinsic from there unless overwritten by passing in as an explicit option which will take precedence.

@brief Specifies the desired target frame time for processing trajectory detection. This can be used for real-time processing of frames, which requires execution with a specific amount of time.

If a frame takes less time than this target, then accuracy of the next frame will be increased (up to a set maximum). The default value is kCMTimeIndefinite, meaning accuracy stays at the predefined maximum.

func VNTrackingRequestFromID 

func VNTrackingRequestFromID(id objc.ID) *VNTrackingRequest

func (*VNTrackingRequest) InputObservation 

func (o *VNTrackingRequest) InputObservation() *VNDetectedObjectObservation

@property property inputObservation @abstract The observation object that defines a region to track. Providing an observation not returned from a tracker (e.g. user-defined, or from a detector) begins a new tracker for the sequence. Providing an observation that was returned from a tracker continues the use of that tracker, to track the region to the next frame. In general, unless documented in the request's documentation, the rectangle must be defined in normalized coordinates (both dimensions normalized to [0,1] with the origin at the lower-left corner).
