Visual Image Deduper

A lightweight Linux desktop utility inspired by classic AntiDupl visual image
comparison workflows. Independent open-source project, not affiliated with or
endorsed by third-party vendors.

VISUAL SCAN & PERCEPTUAL ALGORITHMS
• Scan local folders and mounted drives for visually duplicate and near-similar
photos across JPG, PNG, BMP, GIF, and other standard image formats.
• Choose between Combined Ensemble, dHash Gradient, pHash DCT Frequency, and
aHash Mean Luminance 64-bit perceptual algorithms with an adjustable 70-100%
similarity threshold slider.
• Optional 90/180/270-degree rotated and horizontally mirrored duplicate match
detection plus aspect-ratio verification and live scan metrics.

SIDE-BY-SIDE IMAGE COMPARATOR
• Inspect matched pairs in a split Left vs Right live image canvas showing real
pixel dimensions, image format, file size delta highlighted green/red,
byte-per-pixel compression ratio, edge sharpness score, and EXIF camera/date.
• One-click Keep Left, Keep Right, or Auto-Prune Lower Resolution actions with
safe quarantine or confirmed permanent deletion.

DEFECT CHECK & QUARANTINE RESTORE LOG
• Scan folders for zero-byte, invalid header, truncated, or unreadable image
files and manage safe quarantine with full Restore and plain-text audit log.
• English default interface with instant Vietnamese language toggle.
