Similar Photo Finder

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.
