Struct TrackerVit

Source 
pub struct TrackerVit { /* private fields */ }
Expand description

the VIT tracker is a super lightweight dnn-based general object tracking.

VIT tracker is much faster and extremely lightweight due to special model structure, the model file is about 767KB. Model download link: https://github.com/opencv/opencv_zoo/tree/main/models/object_tracking_vittrack Author: PengyuLiu, 1872918507@qq.com

impl<Mat> ModifyInplace for Mat
where Mat: Boxed,

Source§

unsafe fn modify_inplace<Res>( &mut self, f: impl FnOnce(&Mat, &mut Mat) -> Res, ) -> Res

Helper function to call OpenCV functions that allow in-place modification of a Mat or another similar object. By passing a mutable reference to the Mat to this function your closure will get called with the read reference and a write references to the same Mat. This is unsafe in a general case as it leads to having non-exclusive mutable access to the internal data, but it can be useful for some performance sensitive operations. One example of an OpenCV function that allows such in-place modification is imgproc::threshold. Read more
