Struct LBFLoss

pub struct LBFLoss { /* private fields */ }

The loss LBF assigned to a placing option. Weighted sum of the x_max and y_max of the shape, with the horizontal dimension being more important.
A pure lexicographic comparison (always prioritizing x-axis) would lead to undesirable results due to the continuous nature of the values.

Implementations

impl LBFLoss

pub fn from_bbox(bbox: Rect) -> Self

pub fn from_shape(shape: &SPolygon) -> Self

pub fn cost(&self) -> f32

pub fn tighten_sample_bbox(&self, sample_bbox: Rect) -> Rect

Tightens a sampling Rect to eliminate regions which would never have a lower loss than self.

Trait Implementations

impl Clone for LBFLoss

fn clone(&self) -> LBFLoss

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LBFLoss

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

Formats the value using the given formatter.

impl PartialEq for LBFLoss

fn eq(&self, other: &LBFLoss) -> 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 PartialOrd for LBFLoss

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
