[−][src]Trait opencv::video::prelude::Tracker
Base abstract class for the long-term tracker
Required methods
pub fn as_raw_Tracker(&self) -> *const c_void
[src]
pub fn as_raw_mut_Tracker(&mut self) -> *mut c_void
[src]
Provided methods
pub fn init(
&mut self,
image: &dyn ToInputArray,
bounding_box: Rect
) -> Result<()>
[src]
&mut self,
image: &dyn ToInputArray,
bounding_box: Rect
) -> Result<()>
Initialize the tracker with a known bounding box that surrounded the target
Parameters
- image: The initial frame
- boundingBox: The initial bounding box
pub fn update(
&mut self,
image: &dyn ToInputArray,
bounding_box: &mut Rect
) -> Result<bool>
[src]
&mut self,
image: &dyn ToInputArray,
bounding_box: &mut Rect
) -> 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
Returns
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)
