Configuration for the ForstnerRefiner.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

radius: i32

Half-size of the local gradient window (full window is 2*radius+1). A radius of 2 gives a 5×5 patch — large enough to capture the gradient structure around a corner while staying local.

min_trace: f32

Minimum trace of the structure tensor (sum of eigenvalues). Rejects flat regions where gradient energy is too low. The value 25.0 corresponds roughly to an average gradient magnitude of ~5 per pixel in a 5×5 window (5² = 25), filtering out textureless areas.

min_det: f32

Minimum determinant of the structure tensor (product of eigenvalues). Guards against singular or near-singular systems where the least-squares solution is numerically unstable. 1e-3 is a conservative floor that rejects only truly degenerate cases.

max_condition_number: f32

Maximum ratio of the larger to the smaller eigenvalue. A high condition number indicates an edge rather than a corner (one dominant gradient direction). The threshold 50.0 is permissive — standard Harris/Förstner literature suggests values in the 10–100 range depending on noise level and corner sharpness.

max_offset: f32

Maximum displacement (in pixels) from the initial integer seed to the refined subpixel location. Offsets larger than ~1.5 px suggest the seed was mislocated and the refinement is extrapolating rather than interpolating; such results are rejected.

Trait Implementations

impl Clone for ForstnerConfig

fn clone(&self) -> ForstnerConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ForstnerConfig

impl Debug for ForstnerConfig

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

Formats the value using the given formatter.

impl Default for ForstnerConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ForstnerConfig

where ForstnerConfig: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ForstnerConfig

fn eq(&self, other: &ForstnerConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ForstnerConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
