Struct HashBasedSimilarity 

pub struct HashBasedSimilarity<H> { /* private fields */ }

A similarity metric based on a hash distance threshold.

This adapter allows using a FrameHasher as a SimilarityMetric.

Implementations

impl<H> HashBasedSimilarity<H>

pub fn new(hasher: H, max_distance: u32) -> Self

Create a new hash-based similarity metric.

max_distance is the maximum hash distance that maps to similarity > 0.

Trait Implementations

impl<H> SimilarityMetric for HashBasedSimilarity<H>

where H: FrameHasher,

fn similarity(&self, a: &RgbaImage, b: &RgbaImage) -> f64

Compute similarity between two frames.

fn duplicate_threshold(&self) -> f64

The threshold above which frames are considered duplicates.

fn name(&self) -> &'static str

Get the name of this metric for logging/debugging.

fn are_duplicates(&self, a: &RgbaImage, b: &RgbaImage) -> bool

Check if two frames are duplicates.
