Struct vid_dup_finder_lib::NormalizedTolerance

pub struct NormalizedTolerance { /* private fields */ }

Tolerance to be applied when searching for duplicates.

Formed of independent tolerances in the spatial domain (allowable difference in the shapes of each frame) and in the temporal domain (allowable differences in movement between frames)

Spatial and temporal tolerances are specified as floating point numbers in the inclusive range (0..1). The higher the number, the more two hashes may differ before they are no longer considered a match. A tolerance of 0 implies two videos will only match if the raw bits of their respective hashes are identical. A tolerance of 1 implies two videos will always match no matter the value of their hashes.

Depending on requirements, useful tolerances appear to be in the range (0.0..0.15).

Implementations

impl NormalizedTolerance

pub fn new(value: f64) -> Self

Create a new Tolerance from spatial and temporal values.

Arguments

• spatial: Spatial tolerance in the inclusive range (0..1)
• temporal: Temporal tolerance in the inclusive range (0..1)

pub fn value(&self) -> f64

Trait Implementations

impl Clone for NormalizedTolerance

fn clone(&self) -> NormalizedTolerance

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NormalizedTolerance

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

impl Default for NormalizedTolerance

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<NormalizedTolerance> for NormalizedTolerance

fn eq(&self, other: &NormalizedTolerance) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &NormalizedTolerance) -> bool

This method tests for !=.
