Perceptual duplicate & burst photo finder with pixel diff and safe quarantine
Similar Photo Finder is a desktop perceptual image deduplication tool for finding visually identical, resized, recompressed, and burst-shot photos across PNG, JPEG, WebP, and BMP folders on Linux. An independent Linux desktop alternative to Awesome Duplicate Photo Finder, it computes 64-bit average hash (aHash), gradient difference hash (dHash), and block-mean perceptual hash (pHash) signatures directly on local images with configurable Hamming distance thresholds.
Key Features:
- Perceptual Scanner: Computes real 64-bit aHash, dHash, and block-mean pHash bit signatures across PNG, JPEG, WebP, and BMP collections; groups resized, recompressed, and near-duplicate burst clusters by Hamming distance (0-16 bits) with one-click Auto-Select Lower-Resolution copies.
- Side-by-Side Diff & Safe Move: Dual zoomable image comparison with resolution, file size, Hamming bit-distance, similarity %, and amplified pixel-diff heatmap, plus reversible Move-to-Quarantine folder actions (never auto-deletes files).
- Cluster Report: Displays cluster totals, reclaimable MB, Hamming distance distribution charts, and exports full duplicate audit reports to CSV and JSON.
