Enum PerceptionLevel 

pub enum PerceptionLevel {
    Imperceptible,
    Marginal,
    Subtle,
    Noticeable,
    Degraded,
}

Perceptual quality level based on metric thresholds.

Variants

Imperceptible

DSSIM < 0.0003 - Visually identical.

Marginal

DSSIM < 0.0007 - Only A/B comparison reveals difference.

Subtle

DSSIM < 0.0015 - Barely noticeable.

Noticeable

DSSIM < 0.003 - Visible on inspection.

Degraded

DSSIM >= 0.003 - Clearly visible artifacts.

Implementations

impl PerceptionLevel

pub fn from_dssim(dssim: f64) -> Self

Determine perception level from DSSIM value.

pub fn from_ssimulacra2(score: f64) -> Self

Determine perception level from SSIMULACRA2 value. SSIMULACRA2 is higher-is-better (100 = identical).

pub fn from_butteraugli(score: f64) -> Self

Determine perception level from Butteraugli value. Butteraugli is lower-is-better (<1.0 = imperceptible).

pub fn max_dssim(self) -> f64

Get the maximum DSSIM value for this perception level.

pub fn min_ssimulacra2(self) -> f64

Get the minimum SSIMULACRA2 value for this perception level.

pub fn max_butteraugli(self) -> f64

Get the maximum Butteraugli value for this perception level.

pub fn code(self) -> &'static str

Get a short code for this level.

Trait Implementations

impl Clone for PerceptionLevel

fn clone(&self) -> PerceptionLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PerceptionLevel

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PerceptionLevel

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PerceptionLevel

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

Formats the value using the given formatter.

impl PartialEq for PerceptionLevel

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
