Struct ParetoFront 

pub struct ParetoFront {
    pub points: Vec<RDPoint>,
}

Pareto front of rate-distortion points.

Fields

points: Vec<RDPoint>

Points on the Pareto front (non-dominated).

Implementations

impl ParetoFront

pub fn compute(points: &[RDPoint]) -> Self

Compute the Pareto front from a set of points.

Returns a new ParetoFront containing only the non-dominated points.

pub fn is_empty(&self) -> bool

Check if the front is empty.

pub fn len(&self) -> usize

Get the number of points on the front.

pub fn at_quality(&self, min_quality: f64) -> Vec<&RDPoint>

Get points that achieve at least the target quality.

pub fn at_bpp(&self, max_bpp: f64) -> Vec<&RDPoint>

Get points that achieve at most the target bpp.

pub fn best_at_bpp(&self, max_bpp: f64) -> Option<&RDPoint>

Get the best point (highest quality) at or below the target bpp.

pub fn best_at_quality(&self, min_quality: f64) -> Option<&RDPoint>

Get the most efficient point (lowest bpp) at or above the target quality.

pub fn codecs(&self) -> Vec<&str>

Get unique codecs on the Pareto front.

pub fn filter_codec(&self, codec: &str) -> Vec<&RDPoint>

Filter to points from a specific codec.

pub fn per_codec(points: &[RDPoint]) -> HashMap<String, ParetoFront>

Compute per-codec Pareto fronts.
