Aligned face crops for Face Recognition at One Kilobyte (IJCB 2026)

Aligned face crops used by the IJCB 2026 paper Face Recognition at One Kilobyte: Evaluating Image Compression Algorithms for Barcode-Constrained Biometric Verification. Derived from the MIT-licensed AI-Solutions-KK/face_recognition_dataset (105 identities, 17,534 images) by face detection with a proprietary detector followed by ArcFace-style five-landmark alignment. Both crop resolutions (112 and 224 pixels) live in a single split; the resolution column distinguishes them.

Each record: image (PNG crop), identity (105 unique labels), file_name (source-relative name defining the canonical evaluation ordering), resolution (112 or 224).
