Enum Metric 

pub enum Metric {
    Vmaf,
    Psnr,
    Ssim,
    Ssimulacra2,
    Butteraugli,
    MsSsim,
    Vif,
    Cambi,
    Xpsnr,
}

Quality metric type.

Variants

Vmaf

Netflix VMAF perceptual score (0-100, higher is better).

Psnr

Peak signal-to-noise ratio in dB (higher is better).

Ssim

Structural similarity index (0-1, higher is better).

Ssimulacra2

SSIMULACRA2 perceptual score (higher is better), via the ssimulacra2 CLI.

Butteraugli

Butteraugli perceptual distance (lower is better), via the butteraugli CLI.

MsSsim

Multi-scale SSIM (0-1, higher is better), via libvmaf’s float_ms_ssim.

Vif

Visual information fidelity (higher is better), the mean of libvmaf’s VIF scales.

Cambi

CAMBI banding score (lower is better), via libvmaf’s cambi feature.

Xpsnr

Perceptually-weighted PSNR in dB (higher is better), via FFmpeg’s xpsnr filter.

Trait Implementations

impl Clone for Metric

fn clone(&self) -> Metric

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Metric

impl Debug for Metric

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

Formats the value using the given formatter.

impl Default for Metric

fn default() -> Metric

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Metric

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Metric

impl PartialEq for Metric

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
