Image Deduplicator

Detect and remove exact or similar duplicate images in folders using perceptual and MD5 hashing with configurable similarity and actions.

Find and remove duplicate or similar images in a folder using perceptual hashing. Use when user wants to clean up duplicate images, find near-duplicates, or deduplicate an image dataset.

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/
