Mutable methods for crate::video::Tracker

Required Methods§

Provided Methods§

Source

fn init(&mut self, image: &impl 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
Source

fn update( &mut self, image: &impl 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)

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
