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.
