Wedding Immortalist

Transform wedding photos and video into an eternal, immersive 3D experience. Create living memories that let couples and guests relive the magic forever.

When to Use This Skill

Use for:
- Processing thousands of wedding photos into 3DGS scenes
- Creating theatre-mode experiences where ceremony/reception moments play in-place
- Building face-clustered guest rosters with best-photo selection
- Matching design aesthetics to wedding themes (disco, rustic, beach, modern, queer celebrations)
- AI-curated photo selection per guest with aesthetic scoring

NOT for:
- General photo editing → use native-app-designer
- Non-wedding 3DGS → use drone-inspection-specialist
- Event planning → not a wedding planner
- Video editing without 3D reconstruction

Theme-Adaptive Design

Theme Detection & Matching

Every wedding has a unique aesthetic. Extract and honor it:

Extracting Theme from Photos

# Theme extraction signals
THEME_SIGNALS = {
    'color_palette': 'Dominant colors from venue, florals, attire',
    'lighting_mood': 'Warm/cool, natural/dramatic, string lights/chandeliers',
    'decor_elements': 'Rustic/modern/vintage/eclectic',
    'attire_style': 'Traditional/non-traditional, formal/casual',
    'cultural_markers': 'Religious symbols, cultural traditions',
    'era_aesthetic': '70s disco, 20s gatsby, etc.'
}

3D Gaussian Splatting Pipeline

Photo/Video Ingestion

Optimal Input Strategy:
├── Video: Extract 2-3 fps (80% overlap minimum)
├── Photos: Include ALL photographer shots
├── Phone photos: Guest uploads (georeferenced bonus)
└── Coverage: Ceremony + reception + all spaces

Quality Thresholds:
├── Minimum images per space: 50-100
├── Overlap requirement: 60-80%
├── Blur rejection: Laplacian variance < 100 = skip
└── Exposure: Reject severe over/underexposure

COLMAP Structure from Motion

# Feature extraction
colmap feature_extractor \
  --database_path database.db \
  --image_path images/ \
  --ImageReader.single_camera 0 \
  --SiftExtraction.max_image_size 3200

# Exhaustive matching for comprehensive coverage
colmap exhaustive_matcher \
  --database_path database.db \
  --SiftMatching.guided_matching 1

# Sparse reconstruction
colmap mapper \
  --database_path database.db \
  --image_path images/ \
  --output_path sparse/

# Dense reconstruction (optional, for mesh)
colmap image_undistorter ...
colmap patch_match_stereo ...

3DGS Training

# Wedding-optimized 3DGS settings
WEDDING_3DGS_CONFIG = {
    'iterations': 50_000,          # High quality for permanent archive
    'densify_from_iter': 500,
    'densify_until_iter': 15_000,
    'densification_interval': 100,
    'opacity_reset_interval': 3000,
    'sh_degree': 3,                # Full spherical harmonics for lighting
    'percent_dense': 0.01,
    'densify_grad_threshold': 0.0002,
}

# Multi-space merge strategy
SPACES = ['ceremony', 'cocktail_hour', 'reception', 'photo_booth', 'dance_floor']
# Train each separately, then create unified navigation

Clustering Parameters

CLUSTERING_CONFIG = {
    'min_cluster_size': 3,         # At least 3 photos to form identity
    'min_samples': 2,
    'metric': 'cosine',
    'cluster_selection_epsilon': 0.3,
    'cluster_selection_method': 'eom',
}

# Identity priority for naming
IDENTITY_PRIORITY = [
    'couple_1', 'couple_2',        # The married couple
    'wedding_party',               # Bridesmaids, groomspeople
    'parents',                     # Parents of the couple

    'siblings',
    'extended_family',
    'friends',
    'vendors',                     # Photographer, DJ, etc.
]

Identity Linking Workflow

1. Couple identification: User tags couple in 2-3 photos
2. Wedding party: User identifies key people
3. Auto-propagation: Embeddings match across all photos
4. Guest matching: Optional guest list import for name assignment
5. Manual corrections: UI for fixing mismatches

Aesthetic Scoring

Per-Photo Quality Metrics

AESTHETIC_FEATURES = {
    # Technical quality
    'sharpness': 'Laplacian variance, MTF analysis',
    'exposure': 'Histogram analysis, dynamic range',
    'noise': 'High-ISO detection, grain analysis',

    # Composition
    'rule_of_thirds': 'Subject placement scoring',
    'symmetry': 'For venue/group shots',
    'framing': 'Negative space, balance',

    # Face-specific
    'expression': 'Smile detection, eye openness',
    'blink_detection': 'Eyes closed penalty',
    'gaze_direction': 'Looking at camera vs. candid',
    'face_occlusion': 'Nothing blocking the face',
    'face_lighting': 'Even illumination, no harsh shadows',

    # Emotional
    'genuine_smile': 'Duchenne marker detection',
    'moment_quality': 'Laughter, tears, embraces',
}

Best Photo Selection Per Person

def select_best_photos(cluster_photos, n=5):
    """Select top N photos for a person across all their appearances."""

    scores = []
    for photo in cluster_photos:
        score = (
            0.25 * technical_quality(photo) +
            0.25 * composition_score(photo) +
            0.30 * expression_quality(photo) +
            0.20 * context_diversity(photo, scores)  # Avoid all similar shots
        )
        scores.append((photo, score))

    # Select top N with diversity constraint
    return diverse_top_n(scores, n, diversity_threshold=0.7)

In-Scene Video Projection

Theatre Mode Rendering:
1. User navigates 3DGS scene freely
2. Approaches "moment marker" (glowing orb/frame)
3. Video/slideshow plays IN the 3D space
   ├── On walls where projector was
   ├── Floating frames in dance floor area
   └── Photo booth backdrop location
4. Spatial audio for speeches/music
5. User can pause, scrub, exit to continue exploring

Anti-Patterns

"All Frames, All the Time"

Wrong: Extracting every video frame for 3DGS.
Why: Redundant data, 10x slower processing, no quality improvement.
Right: 2-3 fps extraction with motion-based keyframe selection.

"One Giant Scene"

Wrong: Training single 3DGS for entire venue.
Why: Memory explosion, quality degradation, impossible on consumer hardware.
Right: Train per-space, create unified navigation with seamless transitions.

"Default Clustering Threshold"

Wrong: Using default HDBSCAN settings.
Why: Wedding photos have varying lighting, makeup, angles—need tuning.
Right: Tune per-wedding based on photo count and quality variance.

"Ignoring Theme"

Wrong: Generic white/gray viewer UI for disco wedding.
Why: Destroys the personality and joy of the event.
Right: Extract and honor the couple's aesthetic choices.

"Photographer Only"

Wrong: Using only professional photos.
Why: Misses candid moments, guest perspectives, coverage gaps.
Right: Merge professional + guest photos for complete coverage.
