Struct VideoSegmentDeduplicator 

pub struct VideoSegmentDeduplicator { /* private fields */ }

Finds duplicate video segments across a collection of indexed videos.

Each video is represented as an ordered sequence of SegmentFingerprints. The deduplicator compares all pairs of fingerprint sequences and reports segment-level matches above a configurable similarity threshold.

Implementations

impl VideoSegmentDeduplicator

pub fn new() -> Self

Create a new deduplicator with the default threshold (0.8).

pub fn with_threshold(threshold: f32) -> Self

Create a deduplicator with a custom similarity threshold.

pub fn add_video( &mut self, video_id: &str, fingerprints: Vec<SegmentFingerprint>, )

Register a video’s fingerprint sequence.

pub fn video_count(&self) -> usize

Returns the number of indexed videos.

pub fn is_empty(&self) -> bool

Returns true if no videos have been added.

pub fn find_duplicate_segments(&self) -> Vec<SegmentMatch>

Find all matching segment pairs across all indexed videos.

Performs pairwise comparison between each combination of (video_a, segment_i) × (video_b, segment_j) for all distinct video pairs. Within-video self-comparisons are skipped.

Uses the deduplicator’s configured threshold.

pub fn find_duplicate_segments_with_threshold( &self, threshold: f32, ) -> Vec<SegmentMatch>

Find matching segment pairs using an explicit similarity threshold.

pub fn query( &self, video_id: &str, fingerprints: &[SegmentFingerprint], threshold: f32, ) -> Vec<SegmentMatch>

Find matches between a newly submitted video and all indexed videos without permanently adding it to the index.
