Trait CornerRefiner 

Source 
pub trait CornerRefiner: Sealed {
    // Required methods
    fn radius(&self) -> i32;
    fn refine(

}
Expand description

Trait implemented by the built-in subpixel refinement backends.

§Stability

This trait is sealed via a private supertrait bound and cannot be implemented outside this crate. The built-in implementors are CenterOfMassRefiner, ForstnerRefiner, SaddlePointRefiner, and the Refiner dispatcher. It is not a public extension point: select a backend through RefinerKind rather than implementing this trait.

Required Methods§

Source

fn radius(&self) -> i32

Half-width of the patch the refiner needs around the seed, in input-image pixels. The caller must ensure the seed is at least this many pixels away from every image border before calling refine; violating this contract yields RefineStatus::OutOfBounds.

Source

fn refine(&mut self, seed_xy: [f32; 2], ctx: RefineContext<'_>) -> RefineResult

Attempt to refine the subpixel position of a corner candidate.

seed_xy is the initial [x, y] position in input-image pixels (origin at the top-left corner of the top-left pixel). Returns a RefineResult whose status indicates whether the position was updated.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
