Struct MetricResult 

pub struct MetricResult {
    pub dssim: Option<f64>,
    pub ssimulacra2: Option<f64>,
    pub butteraugli: Option<f64>,
    pub psnr: Option<f64>,
}

Results from metric calculations.

Fields

dssim: Option<f64>

DSSIM value (lower is better, 0 = identical).

ssimulacra2: Option<f64>

SSIMULACRA2 score (higher is better, 100 = identical).

butteraugli: Option<f64>

Butteraugli score (lower is better, <1.0 = imperceptible).

psnr: Option<f64>

PSNR value in dB (higher is better). NOT RECOMMENDED.

Implementations

impl MetricResult

pub fn perception_level(&self) -> Option<PerceptionLevel>

pub fn perception_level_ssimulacra2(&self) -> Option<PerceptionLevel>

Get the perception level based on SSIMULACRA2 value.

pub fn perception_level_butteraugli(&self) -> Option<PerceptionLevel>

Get the perception level based on Butteraugli value.
