Base abstract class for the long-term tracker:

Required methods

`fn as_raw_Tracker(&self) -> *const c_void`

`fn as_raw_mut_Tracker(&mut self) -> *mut c_void`

Provided methods

`fn init( &mut self, image: &dyn ToInputArray, bounding_box: Rect2d ) -> Result<bool>`

Initialize the tracker with a known bounding box that surrounded the target

Parameters

image: The initial frame
boundingBox: The initial bounding box

Returns

True if initialization went succesfully, false otherwise

`fn update( &mut self, image: &dyn ToInputArray, bounding_box: &mut Rect2d ) -> Result<bool>`

Update the tracker, find the new most likely bounding box for the target

Parameters

image: The current frame
boundingBox: The bounding box that represent the new target location, if true was returned, not modified otherwise

True means that target was located and false means that tracker cannot locate target in current frame. Note, that latter does not imply that tracker has failed, maybe target is indeed missing from the frame (say, out of sight)
