Compute Pairwise Similarity Matrix for All Lineup Members — lineup_pairwise

Computes a full pairwise similarity matrix between all faces in a lineup, including the target. Useful for understanding the overall structure of face similarities in the lineup.

Usage

lineup_pairwise_matrix(
  target_path,
  foil_paths,
  model = "ArcFace",
  metric = "cosine",
  detector = "retinaface"
)

Arguments

target_path: Path to target face.
foil_paths: Paths to foil faces.
model: Face recognition model.
metric: Distance metric.
detector: Face detector.

Value

A square matrix of pairwise distances, with row/column names.

Examples

if (FALSE) { # \dontrun{
mat <- lineup_pairwise_matrix("target.jpg", c("foil1.jpg", "foil2.jpg"))
# Visualize with heatmap
heatmap(mat)
} # }
