Enum Refiner 

#[non_exhaustive]
pub enum Refiner {
    CenterOfMass(CenterOfMassRefiner),
    Forstner(ForstnerRefiner),
    SaddlePoint(SaddlePointRefiner),
}

Runtime refiner with reusable scratch buffers.

Constructed from a RefinerKind via Refiner::from_kind. Implements CornerRefiner by dispatching to the selected backend. Reuse across many candidates on the same frame to amortize allocation; scratch buffers are sized at construction and are not reallocated on each call.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CenterOfMass(CenterOfMassRefiner)

5×5 weighted centroid on the response map.

Forstner(ForstnerRefiner)

Gradient structure-tensor refinement on the image patch.

SaddlePoint(SaddlePointRefiner)

Quadratic surface fit on the image patch.

Implementations

impl Refiner

pub fn from_kind(kind: RefinerKind) -> Self

Construct a Refiner from the given kind, allocating scratch buffers at the configured size.

Trait Implementations

impl CornerRefiner for Refiner

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.

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

Attempt to refine the subpixel position of a corner candidate.

impl Debug for Refiner

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
