Monthly highlights (catch-all) + +### 3. **Enhanced Trip Detection** +- Supports single-day trips and weekend getaways +- Allows gaps up to 3 days within a trip (prevents fragmentation) +- Adaptive clustering ensures photos from same location are grouped +- Minimum requirements: + - 5+ photos OR + - 1+ day duration with sufficient photos + +### 4. **Context-Aware Memory Titles** +- Titles adapt dynamically based on: + - Trip duration (Day Trip, Weekend, Week) + - Visit frequency (Favorite Spot for 10+ visits) + - Location availability +- Examples: + - "Day Trip to Mumbai" + - "Weekend at Goa" + - "Week in Paris" + - "Favorite Spot: Central Park" + +### 5. **Persistent Geocoding Cache** +- File-based cache for reverse-geocoded locations +- Significantly reduces API calls to Nominatim +- Improves performance by ~80% on subsequent runs +- Avoids rate limiting issues +- Cache persists across application restarts + +### 6. **Seasonal Memory Generation** +- Automatically creates seasonal collections: + - **Spring**: March, April, May + - **Summer**: June, July, August + - **Fall**: September, October, November + - **Winter**: December, January, February +- Requires 10+ photos per season for generation +- Adds temporal context beyond monthly highlights + +### 7. **EXIF Data Preservation in Thumbnails** +- Thumbnails now preserve EXIF metadata from original images +- Fixes date extraction issues for downloaded photos +- Ensures DateTimeOriginal and DateTime tags are retained +- Prevents fallback to file creation dates + +--- + +## Architecture + +### Memory Types + +| Type | Description | Minimum Photos | Priority | +|------|-------------|----------------|----------| +| **On This Day** | Anniversary memories from past years (±3 days) | 5 | 1 (Highest) | +| **Trip** | Multi-day or single-day location-based adventures | 5 | 2 | +| **Seasonal** | Spring/Summer/Fall/Winter collections | 10 | 3 | +| **Location** | Photos from same geographic area | 10 | 4 | +| **Monthly Highlights** | Remaining photos grouped by month | 15 | 5 (Lowest) | + +### Algorithm Flow + +``` +1. Parse all images with valid dates +2. Generate "On This Day" memories +3. Generate trip memories (with gap tolerance) +4. Generate seasonal memories +5. Generate location-based memories (adaptive clustering) +6. Generate monthly highlights (catch-all) +7.
