A new research paper explores methods for compressing facial images to under 1024 bytes for use in temporary travel documents, aiming to enable machine readability via 2D barcodes. The study evaluates various compression formats including JPEG, JPEG 2000, JPEG XL, JPEG AI, HEIF, AVIF, and WebP, alongside preprocessing techniques like grayscale conversion, smoothing, and resizing. Results indicate that JPEG AI, when optimized, offers the best face recognition performance, particularly for high-quality images, with AVIF and WebP also showing promising outcomes. AI
