Open Model vs Photoroom#

9 examples. Quantitative metrics (MGE, MAE, Connectivity) require ground-truth alpha mattes. Use the view controls on each row to switch between transparency, chroma key, and alpha matte on all outputs. Metric scores are shown as ? until ground truth is added.

Methodology

  • Alpha mattes are grayscale masks encoding per-pixel foreground probability. They capture fine edge detail (hair, fur, semi-transparent regions) that binary masks discard.
  • Metrics are computed by comparing predicted mattes against a ground-truth reference: MGE measures edge sharpness, MAE measures pixel-level accuracy, and Connectivity penalises fragmented foreground regions. All three are lower-is-better.
  • Scores are shown as ? when no ground-truth matte is available for that image. See the alpha matting evaluation benchmark for details on the evaluation methodology.
