CaptureGuide-Bench

CaptureGuide-Bench is the evaluation benchmark for ShutterMuse: Capture-Time Photography Guidance with MLLMs. It evaluates capture-time photography guidance from two complementary perspectives:

• Photographer-side / Composition Recommendation: given the current framing, decide whether it should be kept, refined, or rejected, and recommend composition boxes when refinement is needed.
• Subject-side / Pose Recommendation: given a scene image, recommend a scene-conditioned portrait pose. ShutterMuse predicts COCO-17 human keypoints with visibility states and can render the recommended pose for evaluation.

Photographer-side: Composition Recommendation

• Task: evaluate composition decision and refinement quality.
• Images: photographer-side/composition_benchmark/original_composition/ contains 421 benchmark images.
• Annotations: photographer-side/composition_benchmark/meta_new.json stores image-level composition metadata, textual rationales, scores, and optional composition boxes.
• Main fields:
  • origin: rationale fields for the original framing, including good/bad reasons and composition type labels.
  • composition_boxes: candidate refinement boxes. Each rect is normalized as [x1, y1, x2, y2].
  • score: composition quality score used by the benchmark scripts.

Subject-side: Pose Recommendation

• Task: evaluate scene-conditioned portrait pose recommendation.
• Input images: subject-side/paper-benchmark/ contains 552 scene images.
• Reference images: subject-side/paper-benchmark-gt/ contains the paired reference/ground-truth images with matching file names.
• Evaluation: the ShutterMuse evaluation code compares generated pose visualizations against the paired references using VLM-based and pose-quality metrics.

Usage with ShutterMuse Evaluation

Install the project dependencies following the GitHub repository, then run one benchmark target at a time:

bash evaluation/scripts/run_unified_evaluation.sh photographer-model
bash evaluation/scripts/run_unified_evaluation.sh photographer-baseline
bash evaluation/scripts/run_unified_evaluation.sh subject
bash evaluation/scripts/run_unified_evaluation.sh subject-baseline

Common environment variables include OUTPUT_ROOT, PYTHON_BIN, model checkpoint paths, LoRA checkpoint paths, and API keys such as GEMINI_API_KEY, QWEN_API_KEY, and GPT_API_KEY for VLM-based scoring or API baselines.
