Live Demo and Visualization

Use this sub-skill for demo_superglue.py-style live matching when the goal is to watch matches update against an anchor frame, write output images, or run safely on a remote server without a GUI.

Route elsewhere

• Batch image-pair matching, .npz dumps, pose evaluation, or pair-file validation: ../pair-matching-evaluation/
• Direct Python API work with models.Matching, SuperPoint, SuperGlue, or tensor-level inference: ../programmatic-api/

Use the bundled references

• CLI reference
• Workflows
• Troubleshooting

Bundled helper

• scripts/run_headless_demo_smoke.py: bounded directory-mode smoke helper that always uses --no_display and forces CPU when requested.

Operating notes

• demo_superglue.py uses VideoStreamer to normalize webcam, IP/RTSP, video-file, and directory inputs.
• The first frame becomes the initial anchor; press n to replace it with the current frame.
• make_matching_plot_fast renders confidence-colored lines and optional keypoints; k toggles keypoints in the interactive viewer.
• Prefer --no_display plus --output_dir for remote or headless runs.
• When few or no matches appear, first check resize, model choice, thresholds, and the selected anchor frame.
• Keep this sub-skill focused on visualization and interactive demo flows; do not use it for pair evaluation or Python API guidance.
