Abstract

A novel idea of automatic recovery from photo QR Code is proposed. The photo QR code can be generated by the proposed pyramid QR coding method. The original photo is then embedded into the generated QR code. The experimental result demonstrates that the original photo is with very high quality and the photo QR code can be used for decoding the embedded words or URLs by common QR code decoders.
