Features

• Exact Duplicates: Find images with identical content
• Similar Images: Detect visually similar images (threshold configurable)
• Hash-based: Fast MD5 hashing for exact duplicates
• Perceptual Hash: pHash for finding similar images
• Batch Processing: Process large image folders
• Multiple Actions: List, delete, or move duplicates

Usage

# Find exact duplicates
python scripts/dedupe.py scan /path/to/images/

# Find similar images (90% similarity)
python scripts/dedupe.py scan /path/to/images/ --threshold 90

# Delete duplicates (keeps first occurrence)
python scripts/dedupe.py scan /path/to/images/ --action delete

# Move duplicates to a folder
python scripts/dedupe.py scan /path/to/images/ --action move --output /path/to/dupes/

Examples

$ python scripts/dedupe.py scan ./images/

這是一款質量不錯的圖片去重工具，處理速度快，功能實用，文件說明詳細。它的優勢在於功能完整、使用靈活、安全性好，刪除前會提示確認。不足之處是依賴額外的庫，安裝時需要手動安裝依賴；另外只有命令列介面，對不熟悉命令列的使用者不太友好。總體而言，是一款專業可靠的圖片清理工具。
