Struct AlignmentMatrix 

pub struct AlignmentMatrix {
    pub tracks: Vec<String>,
    pub offsets: Vec<Vec<i64>>,
}

Pairwise frame-offset matrix between a set of tracks.

Fields

tracks: Vec<String>

Track IDs (row/column labels).

offsets: Vec<Vec<i64>>

offsets[i][j] = frame offset of track j relative to track i.

Implementations

impl AlignmentMatrix

pub fn from_alignments( track_ids: &[&str], alignments: &[TrackAlignment], ) -> Self

Create a new alignment matrix from a list of pairwise TrackAlignments.

The matrix is filled symmetrically: if alignment.offset_frames is the offset from reference_id to aligned_id, then [ref_idx][aln_idx] = offset and [aln_idx][ref_idx] = -offset.

pub fn compute_global_offsets(&self) -> Vec<i64>

Compute a single global offset for each track (relative to track 0) using a least-squares approach.

The method averages all available pairwise constraints for each track, propagating offsets transitively through the matrix. Track 0 is fixed at offset 0.
