Struct SaddlePointConfig 

#[non_exhaustive]
pub struct SaddlePointConfig {
    pub radius: i32,
    pub det_margin: f32,
    pub max_offset: f32,
    pub min_abs_det: f32,
}

Configuration for the SaddlePointRefiner.

All thresholds below are advanced tuning knobs. The defaults are appropriate for most scenes; adjust only if you observe excessive rejection or acceptance of clearly-wrong refinements.

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 image patch used for the surface fit (full patch is 2·radius+1 × 2·radius+1). Default is 2 (5×5 patch).

Advanced tuning.

det_margin: f32

The Hessian determinant of the fitted quadratic must be more negative than -det_margin (i.e. det(H) < -det_margin) for a saddle to be confirmed. Increase to require a sharper saddle before accepting.

Advanced tuning.

max_offset: f32

Maximum displacement (pixels) from the seed to the fitted stationary point. Refinements with a larger displacement are rejected. Mirrors ForstnerConfig::max_offset.

Advanced tuning.

min_abs_det: f32

Minimum absolute value of det(H). Rejects near-flat surfaces where the determinant is too close to zero to be meaningful.

Advanced tuning.

Trait Implementations

impl Clone for SaddlePointConfig

fn clone(&self) -> SaddlePointConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SaddlePointConfig

impl Debug for SaddlePointConfig

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

Formats the value using the given formatter.

impl Default for SaddlePointConfig

fn default() -> SaddlePointConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SaddlePointConfig

where SaddlePointConfig: Default,

fn deserialize<__D>( __deserializer: __D, ) -> Result<SaddlePointConfig, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SaddlePointConfig

fn eq(&self, other: &SaddlePointConfig) -> 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 SaddlePointConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
