Abstract

A Holographic-QR (H-QR) code is a hologram numerically generated from a QR code pattern. When an H-QR hologram is illuminated by a coherent beam, the QR code it represents will be reconstructed as a visually observable image. A H-QR code is less sensitive to damage than the classical QR code, but is still unreadable if the defective area is too extensive. In this paper, we propose a fast method to further strengthen the resiliency of the H-QR code to large scale damage. Experimental evaluation demonstrates that with our proposed algorithm, a QR code can be fully reconstructed from a H-QR hologram that has been damaged in over 50% of its area.
